phosphors were prepared by sol-gel method. Their structure and luminescence properties were characterized by X-ray diffraction (XRD) analysis and fluorescence spectrometry (FL). The preparation conditions of the precursor synthesis

including the Dy

concentration and crystallization temperature were investigated. The results showed that the luminescence intensity of YAl

∶Dy

is the biggest at the calcination temperature of 1 100 ℃.The optimum doping mole fraction of Dy

ions was

=0.05. The main emission peak was about 575 nm excited at 774 nm. The YAl

)

∶Dy

phosphors can convert spectra band from 700 to 900 nm and from 290 to 490 nm into visible light around 575 nm which is absorbed strongly by the dye sensitized solar cells.
