(See Annex 1)

         I have started research activities at the end of 1965 on Photoluminescence  Processes and Excited State Dynamics of Bi3+ ions in (Ca,Sr) antimonates, (Y,Sc,Gd) sesquioxides and (Y,Sc,Gd) Orthovanadates, and was awarded “Docteur ès Sciences” (Third Cycle on Spectronomy) on March 1st, 1968 and “Docteur ès Sciences Physiques d’Etat” on June 1st, 1970 under the guidance of Dr. Françoise GAUME, CNRS Director of Research, and Prof. Daniel CURIE, Professor at the University of Paris.

Then, after 1970, as so-called “Maître-Assistant of the University of Lyon”, Dr. Françoise GAUME asked me, to help her for assisting new PhD students joining her at the LPCML group. From 1968 I have trained few PhD students up to my nomination of Professor of the UCBLyon1 (1981).  I am very pride by this period of my scientific life, for which in addition of my regular lectures with undergraduate students, I spent my research time in co-operation with Dr. Françoise GAUME to train new PhD researchers as C.PEDRINI, B. JACQUIER, R. MONCORGE, B.MOINE, M.F. JOUBERT, who were all nominated CNRS Researchers later on.  I have obviously to mention during these years the first mutual works of my long co-operation with prof. R.Reisfeld from the Hebrew University of Jerusalem (Israel) (references n° 452, 451, 444, 443, 441, 435, 430, 427, 426, 421, 420) and two invitations in the USA which were also very important for my future scientific activities, as Associated Researcher at the Wisconsin University, Department of Physics with Professor W.Yen. (6 months on July-December 1978) and as Invited Professor at the Oklahoma State University, Department of Physics with Professor Powell (3 months on June-September 1982) (references 436, 414, 411, 407, 377, 346).

          Two years later, after my nomination of Full Professor, Dr. Françoise GAUME recommended me in 1983 to CNRS Scientific Administration in Paris, in order to be her successor at the head of the LPCML laboratory after her retirement. I was confirmed by this proposition and also accepted by the LPCML Committee in Lyon and I was very pride to be Dr. Françoise GAUME’s successor. In France, CNRS laboratory directors are nominated for only 4 years, but it is possible to continue two or even three times, depending of the acceptance of CNRS in Paris. I was renewed and finally able to be Director till 1994. In 1995, I have received another responsibility from the CNRS Administration, as Director of the CNRS French Research Group (GDR 1148) on solid-state laser type materials till 2002, gathering all French public and private laboratories working in this area.

          I have continued my research activities at LPCML with strong co-operations with The Polish Academy of Sciences and the University of Wroclaw in Poland, the Tohoku University in Sendai (Japan) and I have accepted to be representative of the Physics and Chemistry fields as a Member of the National Committee for the Evaluation of the French Universities (CNE) (2003-2007), among 25 members for all academic fields in France.

          My approach was to stimulate basic and sometimes applied research on physical chemistry of inorganic luminescent materials for my group and also for other groups at the LPCML, by the conjugation of both, elaboration techniques, structural characterizations, spectroscopic analysis and tests of applications with materials used for inorganic phosphors, laser materials and nonlinear crystals.

          The elaboration of samples has been made in relationship with experts in chemistry either in Lyon or abroad. The main polycrystalline phases have been prepared and characterized at LPCML and the oxide glassy phases have been synthetized at the Hebrew University of Jerusalem, at Saint-Gobain Company and at the Department of glass fluorides in Rennes. After 1983, we have spent a lot of efforts to find enough financial support to fixe new furnaces to grow single crystals. The crystal growth techniques used were Czochralski (CZ), Laser Heated Pedestal Growth (LHPG), Floating crystal, µ-Pulling-Down which have been installed in LPCML. We have also established in 1996 a fruitful co-operation with the Fukuda’s laboratory at the Tohoku University in Sendai (Japan) to get the best optical quality luminescent crystals we need mainly with laser crystals and nonlinear crystals. Since 10 years we also work in co-operation on nanocrystals and nanoceramics with Polish teams in Wroclaw.

         The Structural characterizations are EPMA (Electron Probe Microscopy Analysis), X-ray Diffractometry, Small angle x-ray scattering, imaging confocal microscopy (ICM) and transmission electronic microscopy (TEM).

          The spectroscopic techniques are transient and steady-state spectroscopic between 4K and 300K, like absorption, excitation, emission, decays of fluorescence in UV, visible, IR, by using CW and pulsed tunable laser

spectroscopy techniques; Time-Resolved Spectroscopy, Site-selective

Spectroscopy, Fluorescence Line Narrowing Spectroscopy, Excites-State

Absorption, Two-Photon Absorption, Raman spectroscopy,

Thermoluminescence (10-600K)

         Laser tests and nonlinear generations into pumping with lasers, laser- diodes and flash-lamps are done on the most promising materials.

         We have investigated, by using mentioned spectroscopic tools, processes involved by up and down conversions, excited state dynamics, energy transfer mechanisms in materials which are doped by the following luminescent ions:

-heavy ions like Bi3+ and Pb2+,

-rare earth ions (Ce3+,  Pr3+, Nd3+, Sm3+, Eu3+, Gd3+, Tb3+, Ho3+, Er3+, Tm3+, Yb3+),

-metal transition ions (Ti3+, 4+, Cr3+,4+,5+,6+, Mn 2+,3+,4+, Ni2+, Co2+, V2+,3+.

         The most important scientific programs were focused on the understanding of the excited state dynamics and relations between structures and optical properties in luminescent materials (polycrystals, glasses, glass-ceramics, today ceramics and now days nanomaterials) :

1. Heavy ions: d10 s2 configuration, Bi3+ and Pb2+ mercury-type ions

1.1. Spectroscopy and Excited state dynamics of Bi3+-doped oxide materials

1.2. Spectroscopy and Excited state dynamics of Pb2+-doped apatites

2. Transition metal ions: 3dn configuration

2.1. Deep program on Cr 3+ -doped crystals/glasses

-Nucleation in Cr3+ ions-doped oxide glasses

-Cr3+ as a probe ion in garnets, magnetoplumbites, spinels, niobates

-Fano effect between 2E and 4T2 levels

-Model of Cr3+ multisites . Application to (Ca,Zr)GGG garnets

-Effect of cation invertion in garnets on Cr3+ spectroscopy

-Four-Wave mixing technique applied to energy transfer of Cr3+ ions in garnets

-Laser spectroscopy of Cr3+-doped nonlinear niobate crystals, especially of stoichiometric and congruent LiNbO3

2.2. Other transition metal ions

-Ti3+,4+, Cr3+,4+,5+,6+, Mn2+,3+,4+, Ni2+, Co2+, V2+,3+,spectroscopies

3. Rare earth ions: 4fn configuration: Ce3+, Nd3+, Ho3+, Er3+, Tm3+, Yb3+

3.1.Deep program on Yb3+-doped Laser materials

- Yb3+-doped cubic laser crystals:

YAG, GGG, LuAG, substituted GGG Garnets,

Y2O3, Sc2O3, Gd2O3, Lu2O3 sesquioxides,

MgAl2O4, ZnAl2O4 spinels,

KY3F10, CaF2 fluorides

- Yb3+- doped non cubic laser crystals

YAP perovskite,

KY(WO4)2, KGd(WO4)2 monoclinic tungstates

Apatites: a few compositions by µ-PD  and Ca8La2(PO4)6O2 by CZ

- Yb3+- laser silicate glasses

- Yb3+- doped laser ceramics

Main advances on Yb3+ and other rare earth ions-doped laser materials: Figure-of-Merit, energy transfers, avalanche and looping mechanisms, concentration quenching mechanisms, gain model, optimization of laser, segregation of rare earth ions in ceramics

3.2. Phosphors for white lighting

Ce3+/Eu2+/Eu3+-doped silicate glass phosphor and UV/blue LEDs as circadian response for white lighting.

3.3. Nanomaterials

Rare earth (Eu3+, Yb3+)-doped cubic/non-cubic nanomaterials (BaTiO3,YAG, spinels) and rare earth stoichiometric nanomaterials for luminescent concentrators in solar cells.

         We have added other complementary techniques to the spectroscopic techniques which have lead to few pioneer results. A few examples are, RBS (Rutherford Back Scattering) channeling to locate the place of rare earth cations in LiNbO3, SAXS (Small Angle X-ray Scattering) for the structural evolution of doped-xerogels during thermal treatments, TEM (Transmission Electronic Microscopy) to separate crystalline and glassy phases in optical glass-ceramics, and to detect phases at the grain boundaries and measurement of rare earth segregation in optical ceramics depending on the nature of the luminescent dopant, Imaging Confocal Microscopy (ICM) using fluorescence of Ce3+ in grains and grain boundaries of ceramics, EXAFS spectroscopy, EPR for characterization of transition metal ions.

          Naturally, we have accompanied all theoretical and experimental results by using models, both, already known but in a more creative way, from our personal ideas.

         Main research activities can be seen from the titles of both, each of the 488 published articles and 5 under publication in Annex 2, of each oral communication I have been invited to present official international conferences in Annex 3, official international and national Schools in Annex 4 and of each PhD thesis I have supervised in Annex 5.
