Paper Abstract

The luminescence properties of the Nd3+:LaAlO3 nanocrystalline powders characterized by different sizes of grains in the range of 25-50 nm were investigated. The effect of the nanocrystallites sizes on the luminescence behavior of Nd3+ was observed. In particular decreasing the grain sizes was found to increase emission from the thermally populated 4F5/2 state. It's intensity increased with the increase of excitation power density. The spectroscopic parameters of Nd3+ doped LaAlO3 nanocrystallites were determined from luminescence spectra by using the Judd-Ofelt method and compared to those obtained for a single crystal of Nd3+:LaAlO3.
