摘要

Lutetium oxide (Lu 2 O 3 ) films were prepared by a simple Pechini sol-gel method with LuCl 3 ·6H 2 O as precursor for the first time. Thermogravimetric analysis and differential thermal analysis were used to study the thermal chemistry properties of dried gel. Structural properties of Lu 2 O 3 films heat-treated at different temperature were investigated through X-ray diffraction and Fourier transform infrared spectroscopy. The results show that Lu 2 O 3 starts to crystallize at about 400 °C and the crystallite size increases with the increasing annealing temperature. The dopant Eu 3+ presents its typical emission in Lu 2 O 3 :Eu films. The effect of heat-treatment temperature on the luminescent properties (broadening of emission peak and change of lifetimes of energy level) of the films was also discussed.
