| 中文摘要 | cawo4 phosphor films doped with rare-earth ions (eu3+, dy-,(3+) sm3+, er3+) were prepared by the pechini sol-gel process. x-ray diffraction (xrd), fourier transform infrared spectroscopy, thermogravimetric and differential thermal analysis, atomic force microscopy, and photoluminescence spectra, as well as lifetimes, were used to characterize the resulting powders and films. the results of the xrd analysis indicated that the films began to crystallize at 400degreesc and that the crystallinity increased with elevation of the annealing temperature. the doped rare-earth ions showed their characteristic emissions in crystalline cawo4 phosphor films due to energy transfer from wo42- groups to them. both the lifetimes and pl intensities of the doped rare-earth ions increased with increasing annealing temperature, from 500 to 900degreesc, and the optimum concentrations for eu3+, dy3+, sm3+, er3+ were determined as 30, 1.5, 1.5, 0.5 at.% of ca2+ in cawo4 films annealed at 900degreesc, respectively. |
