Аннотация доклада:
We found, that the modification of luminescent properties by Lu2O3 doping in Lu3Al5O12:Ce3++Lu2O3 is drastically different is comparison with Y3Al5O12:Ce3++Lu2O3 due a redistribution of optically active Ce3+ ions between initial Lu3Al5O12 and lutetium oxide Lu2O3 phase during the colloid chemical synthesis, resulting in suppression of luminescence intensity. The obtained results demonstrate that oxide doping effects on structural and luminescent properties of “garnet+oxide” system have a complex character, and one needs to take into account several factors. They include not only diffusion processes of Ce3+ ions between system components, but also possible formation of new structural phases and stable defect regions at phase interface, and optically active or inactive state of activator ion in a specific structural environment.
