| 中文摘要 | in this presentation, nanocrystalline yvo4:a (a=eu3+, dy3+, sm3+, er3+) phosphor films and their patterning were fabricated by a pechini sol-gel process combined with a soft lithography (micro-molding in capillaries). xrd, ft-ir, afm and optical microscope, absorption spectra, 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 400 degrees c and the crystallinity increased with the increase of annealing temperatures. transparent nonpattemed phosphor films were uniform and crack free, which mainly consisted of grains with an average size of 90nm. patterned crystalline phosphor film bands with different widths (5-30 mu m) were obtained. the doped rare earth ions (a) showed their characteristic emission in crystalline yvo4 phosphor films due to an efficient energy transfer from vanadate groups to them. the sm3+ and er3+ ions also showed upconversion luminescence in yvo4 film host. the optimum concentration for eu3+ was determined to be 7 mol% and those for dy3+, sm3+, er3+ were 2 mol% of y3+ in yvo4 films, respectively. |
