中文摘要	nanocrystalline y2o3:eu3+ phosphor films and their patterning were fabricated by a pechini sol-gel process combined with a soft lithography. x-ray diffraction (xrd), thermogravimetric and differential thermal analysis (tg-dta), atomic force microscopy (afm), optical microscopy, uv/vis transmission and photoluminescence (pl) spectra as well as lifetimes were used to characterize the resulting films. the results of xrd indicated that the films began to crystallize at 500 degreesc and the crystallinity increased with the elevation of annealing temperatures. uniform and crack free non-patterned phosphor films were obtained, which mainly consisted of grains with an average size of 70 nm. using micro-molding in capillaries technique, we obtained homogeneous and defects-free patterned gel and crystalline phosphor films with different stripe widths (5, 10, 20 and 50 mum). significant shrinkage (50%) was observed in the patterned films during the heat treatment process. the doped eu3+ showed its characteristic emission in crystalline y2o3 phosphor films due to an efficient energy transfer from y2o3 host to them. both the lifetimes and pl intensity of the eu3+ increased with increasing the annealing temperature from 500 to 900 degreesc, and the optimum concentrations for eu3+ were determined to be 5 mol%.
