In order to obtain clear-cut information on the factors which favour the discrimination between trivalent actinides and lanthanides, we investigated the complexation of the tris(cyclopentadienyl) Ce(III) and U(III) compounds, (RCp)3M (R = tBu, SiMe3), with a series of monocyclic azines with distinct Lewis basicity and reduction potential. Coordination of pyrazine and 4,4' and 2,2'-bipyridines on the (RCp)3M complexes has also been studied. Of major interest is the reversible oxidation of the (RCp)3U species into the uranium(IV) [(RCp)3U]2(pyz) complexes by pyrazine. The presence of cooperativity in the binding of the cyclopentadienyl groups by U(III), due to late appearance of back-bonding, leads to a greater stabilization of the uranium(III) complexes. Complexation of the species Cp*2MI (M = Ce, U) by 2,2'-bipyridine, phenanthroline and terpyridine affords the adducts [Cp*2M(L)]I. For L = bipy and terpy, these compounds are reduced into Cp*2M(L). The magnetic data for [Cp*2M(terpy)]I and Cp*2M(terpy) are consistent with Ce(III) and U(III) species, with the formulation Cp*2MIII(terpy•–). An electron transfer reaction between these species was observed in NMR. Reactions of the [Cp*2M(terpy)]I and Cp*2M(terpy) complexes with H• and H+ donor reagents lead to a clear differentiation of these trivalent ions. We studied the coordination of the stable N-heterocyclic carbene and isonitrile molecules on (RCp)3M and Cp*2MI ; competition reactions and comparison of the crystal structures of the carbene compounds reveal the much better affinity of the NHC and tBuNC ligands for the 5f rather than for the 4f ion

This work is divided into two parts : The first part is dedicated to synthesis of symmetrical or unsymmetrical bis tetraazamacrocyclic compounds, via bis aminal derivatives of cyclam and cyclen. This method is extended to linear and cyclic tris macrocyclic compounds. In the second part, we report the complexation of these poly tetraazamacrocycles with transition metal ions : Cu(II) and Ni(II). The complexes have been fully investigated by cyclic voltammetry and EPR to determine possible interactions between the metal centres. Carboxylic pendant arms have been grafted on some bis tetraazamacrocycles to coordinate Gd (III). Resulting complexes present better properties that DOTA Gd(III) as nuclear magnetic resonance imaging (MRI) contrast agents

This study has shown that substitution of selenium by sulfur in a germanium-free glass improves its optical properties without decreasing its mechanical strength. It has also been proven that it is possible to synthesize chalcogenide glasses reproducibly in an open system. Structural investigations carried out on a sulfide glass system submitted to a heat treatment indicate a two-step crystallization process. Erbium ions, whose nucleating action on this glass appeared to be stronger than the action of neodymium ions, can be incorporated in the crystalline phases, which leads to stronger light emission peaks in the glass-ceramics compared to the base glass. Adding ytterbium to erbium doped sulfide glass-ceramics increases visible light emission of the erbium ions by upconversion if they are pumped in the near infrared

Biological thermal modifications are common events during abnormal cellular metabolic activities. Indeed, thermal aberrations – such as an increase in local tissue temperature – are directly related to the detection of inflamed areas, the presence of tumors, or other diseases. In addition to contributing to the diagnosis of diseases, the determination of local temperature in biological systems can also help with their treatment. For instance, in hyperthermia, the increase in temperature must be induced in tumor tissues up to cytotoxic levels in order to kill cancer cells and therefore, it assists in the cancer treatment. However, the increase in temperature must be carried out in a controlled and well-localized manner to target cancer cells, while avoiding overheating of surrounding healthy tissue. Furthermore, to determine such biological aberrations, temperature variations must be accurately determined. The thermometric performance of the nanothermometers was determined by calculating the relative thermal sensitivity (S_r) using the ratiometric luminescence intensity approach. Furthermore, our study made it possible to raise some hypotheses that can effectively contribute to the thermometric performance of thermal probes. We use the technique of the intensity ratio of two luminescence peaks for which the values of S_r can be optimized by co-doping the nanocrystals with two, or more, Ln3+ ions and by using oxide matrices presenting different phonon energies. Thus, due to its generic nature and synthesis flexibility, the Pechini method was chosen to synthesize several oxide matrices, Y2O3, Y2Ge2O7, Y3Al5O12 (YAG), Y3BO6 and YBO3. The nanocrystals were firstly monodoped with Nd3+ and posteriorly, codoped with Nd3+ -Yb3+ to improve the thermal probe properties within the biological windows of near infrared. In addition, we optimized the doping concentrations in the host matrices for greater efficiency in luminescence detection in biological organisms. We experimentally observed that Sr values are strongly impacted to the phonon energy of the matrix. We analyzed that by Nd3+ -Yb3+ codoping the thermometric performance of nanocrystals is improved compared to nanocrystals mono doped with Nd3+. Our study of different oxides shows that the YAG and Y2O3 matrices are the most promising matrices for the luminescence nanothermometry in vivo application. Lastly, YAG individual nanocrystals (non-agglomerated as in the case of Pechini syntheses) of size 60 nm and controlled morphology were obtained in solution by the solvothermal method to advance in further studies in biological applications. We observed that the YAG nanothermometers suitable for the purpose have a S_r equal to 0.47 %·K-1 and a thermal resolution of 0.3 K. In vivo experimental tests are required to validate the findings of this study; however, our results obtained on the performance of YAG: Nd3+ -Yb3+ nanocrystals has been showing high potential for in vivo applications of ratiometric luminescence nanothermometry

The compact and cost-effective coherent source emitting in yellow and green region (500 ~ 600 nm) is of great interest in the fields of optical display, medicine and biology. Presently, the pervasive methods for generating visible lasers include laser diode (LD), nonlinear frequency conversion, and direct pumping of the gain medium doped with luminescent ions (Pr3+, Sm3+, Tb3+, etc.). In general, Dy3+ as well as Tb3+ have excellent luminescence properties, but the extremely small absorption cross-section is the biggest obstacle to their application and development.This PhD work was aimed at the investigation of novel visible laser crystals on the basis of the Dy3+ or Tb3+ doped oxide crystals, by introducing Ce3+, Eu3+ or Yb3+ as sensitizer ions for enhancing the luminescence properties. Different co-doping proposals including the sensitizer selection and the doping concentration optimization were implemented. In the meantime, various oxide hosts such as CaYAlO4, CaYAl3O7, Lu3Al3Ga2O12, Ca3Sc2Si3O12, Y3Sc2Al3O12 and YAlO3 were selected and synthesized and the co-doped laser crystals based on the above hosts were grown by the Czochralski method. The corresponding optical spectroscopy properties including the absorption, emission, fluorescence lifetime and energy transfer were comprehensively evaluated
