摘要：

Ce3+ and Tb3+ co-doped Strontium Pyroborate phosphors were synthesized by the solid-state method. The luminescent properties of phosphors were investigated by using the photoluminescence emission and excitation spectra. Under the excitation of near ultraviolet (n-UV) light, Ce3+ and Tb3+ co-doped Strontium Pyroborate phosphors exhibited blue emission corresponding to the f-d transition of Ce3+ ions and green emission bands corresponding to the f-f transition of Tb3+ ions, respectively. In the Ce3+ and Tb3+ co-activated samples the Ce3+ ions strongly sensitize the luminescence of the Tb ions. The Ce3+ and Tb3+ co-doped Strontium Pyroborate phosphor could be considered as one of double emission phosphor for n-UV excited white light emitting diodes.
