The Yttria stabilized Zirconia nanocrystals were synthezed by microwave driven hidrothermal method. The luminescance spectra, decay kinetics and luminescence intensity dependence on temperature were measured for different size nanocrystals. Steady-state luminescence was excited by X-rays, time-resolved luminescence study was prepared under pulsed laser beam (4,66eV, 2ns) and under pulsed electron beam (270 keV, 10ns) excitation. It is shown the luminescence spectra are similar for all nanocrystal sizes, whereas the intensity of luminescence is nanocrystal size dependent. The origin of this dependence was interaction between electronic excitations and intrinsic defects. The luminescence decay kinetics (both, under laser and electron beam excitation) reveals the fast initial decay followed by slower one. The decay of luminescence did not obey a simple exponential or hyperbolic rule, indicating more complicated recombination process. The time–resolved spectra and decay kinetics analysis confirms more than one kind of recombination centers were involved. Possible models of luminiscence centres and recombination processes are discussed. The luminescence intensity and decay time dependence on temperature gaves an evidence that two processes – the luminescence center destruction and non – radiative electron transitions – were responsible for luminescence quenching observed. The relative contribution of these processes in luminescence quenching depends on nanocrystal size.
