The scanning electronic microscope （SEM） showed that the compact and crack-free LaVO4：Dy3＋ film could be obtained at a suitable solution concentration. The deposited films could absorb the ultraviolet light below 400 nm and were transparent in the visible and infrared region as evidenced by the transmission spectra, and the photolumines- cence spectra exhibited the characteristic emissions of Dy3＋ peaking at 484 （blue） and 576 （yellow） nm due to the transitions of 4F9/2→6Hls/2 and 4F9/2→6H13/2, respectively. The potential application of LaVOa：Dy3＋ film in the dye-sensitized solar cell （DSSC） was also discussed.展开更多
