What is Highly enhanced photoluminescence and X-ray excited luminescence of Li doped Gd2O3:Eu3+ thin films about?

Transparent Li-doped Gd 2 O 3 :Eu 3C thin-film phosphors were prepared by a modified sol-gel method. The effect of the Li C ions on luminescent properties of the thin film was investigated. The results indicated that incorporation of Li C ions into Gd 2 O 3 lattice could result in a remarkable increase on photoluminescence or X-ray excited luminescence, and the strongest emission was observed from Gd 1.84 Li 0.08 Eu 0.08 O 3Kd film, in which the intensity was increased by a factor of 1.9 or 2.3 in comparison with that of Gd 1.92 Eu 0.08 O 3 film. And it could be achieved the highest intensity for sintering the Gd 1.84 Li 0.08 Eu 0.08 O 3Kd film at 700 8C. Such a temperature is much lower than the typical solid-state reaction temperature for its powder phosphors. This kind of transparent thin-film phosphors may promise for application to micro X-ray imaging system.
