| Abstract: | It was rstudied in this paper that rare earth ions affect luminescent intensity,excitation spectra,emission spectra and decay curve of blue-purple night-luminous phosphor CaS:Bi,Cu. It was found that the rare earth ions with 4f~n and 4f~(14-n) have similar effect to increase properties of CaS:Bi,Cu phosphor,and that CaS:Bi,Cu,Tm is blue-purple night-luminous phosphor which can be practically used. |
