Paper Abstract

In combination with pyrolysis processing, the smooth, transparent and dense Gd2O3:Eu3+ thin films have been prepared by sol-gel technique under the absence of inert atmosphere. Comparing with powder samples, there is a remarkable variation in the excitation spectrum of thin film, which indicates that the energy transfer between Gd2O3 host lattice and Eu3+ activator is more effective in film configuration. The results of emission spectra excited by UV indicate that the optimal concentration of Eu3+ is about 10 mol.%. The phenomenon of luminescence reduction was observed for the films annealed at 1000°C, which results from the phase transition of cubic to monoclinic structure. The emission spectrum under X-ray excitation is also presented.
