Full textMedicine is increasingly interested in nanometric systems for the early detection of malignant cells, their treatment or understanding of biological mechanisms. Fluorescent nanoparticles and harmonic nanocrystals with interesting non-linear properties have been studied as contrast agents for biomedical imaging.In this work, we explored a non-centrosymmetric material whose matrix allows a doping of lanthanide ions in order to develop multifunctional probes, i. e. both luminescent and harmonic. We focused on non-centrosymmetric iodate phase: alpha lanthanum iodate, α-La(IO3)3. First, we developed microwave-assisted hydrothermal syntheses to crystallize the alpha phase and produce nano-sized particles (< 100 nm). The presence of many pseudo-polymorphs requires precise control of the synthesis parameters, in particular the synthesis temperature, to obtain exclusively nanoparticles of α-La(IO3)3. The study of different reaction intermediates (La(IO3)3(OH2), La(IO3)2.66(OH)0.33) allowed us to identify a phase transformation between these compounds and the phase α-La(IO3)3. Secondly, we used two optical devices to evaluate the second harmonic generation efficiency of the synthesized α-La(IO3)3 nanocrystals: one set-up allowed us to study individual α-La(IO3)3 nanocrystals and the other used an ensemble of α-La(IO3)3 nanocrystals in suspension in a solvent. The latter, based on Hyper-Rayleigh scattering, quantified the non-linear response of nanocrystals α-La(IO3)3 with a diameter of 20-50 nm and allowed us to determine a non-linear coefficient < d > of 8 pm.V-1, a value comparable to the ones obtained for other harmonic nanocrystals such as BaTiO3 or LiNbO3. Finally, we showed the possibility of incorporating lanthanide ions such as Er3+ and Yb3+ into these lanthanum iodate nanocrystals, leading to α-La1-x-yYbyErx(IO3)3 nanocrystals. These nanocrystals are still active in second harmonic generation and simultaneously emit a photoluminescence signal. Thus, for excitation in the near infrared (800 nm or 980 nm for instance), we simultaneously observed a signal of second harmonic and a photoluminescence signal based on up-conversion processes. We demonstrated the interest of an Yb3+/Er3+ co-doping for an optimization of the up-conversion signal under excitation at 980 nm. Thus, Er3+ and Yb3+-doped nanocrystals of α-La(IO3)3 exhibit simultaneous emission of second harmonic generation and photoluminescence. The combination of these two properties makes it possible to consider using these bifunctional nanocrystals for conventional luminescence imaging, while coupling it with multiphoton imaging, which is more expensive but has significant advantages (scan speed, better spatial selectivity, polarization sensitivity)

Full textThe aim of this PhD project is to develop the synthesis of fluoride nanoparticles doped with rare earth or transition metal ions for novel applications in nanophotonics, such as probes for thermal imaging at nanoscale. Nanoparticles can also use for the coating of photovoltaic cells to optimize their yield by absorption of a larger range of wavelengths. The particularity of the fluoride particles doped with the adequate ions, is to exhibit, for example, efficient up-conversion processes or efficient infrared emissions, due to the high ionic nature of the metal-fluorine bonding. Emphasis will be put on the development and optimization of low-temperature millifluidic processes which are able to ensure the chemical, morphology and size homogeneities of the as obtained nanoparticles. The synthesized nanoparticles will be characterized (chemical composition, size distribution, morphology) as well as their physical properties, particularly the luminescence properties. The possibility of a migration of the millifluidic synthesis processes to microfluidic processes should be explored
