Abstract

Europium-doped gadolinium oxide films were prepared by the sol-gel method and spin-coating technique. The emission spectra of the films were investigated under both UV and X-ray excitation. Three kinds of cross-linking agents (EG, PEG200 and PEG400) were added to increase the thickness of the films. The luminescence intensity and the thickness of different film indicated PEG200 was the best cross-linking agent among the three compounds. At the same time, UV assisted technique as well as thermal decomposition technique have been introduced to reduce the film forming period and to prepare high quality luminescence films, and they can accelerate the film deposition process extremely.
