ABSTRACT

A series of Sr1 xCaxGa2S4 : Ce,Na phosphors have been synthesized by solid-state reaction. The photoluminescenceand structural properties of Sr1 xCaxGa2S4 : Ce,Na have been examined. The Sr1 xCaxGa2S4 : Ce,Na phosphors have a strongSrGa2S4 : Ce,Na are located at 448 nm and 485 nm. The partial replacement of Sr by Ca in Sr1 xCaxGa2S4 : Ce,Na causes ared shift of emission wavelengths. The Sr1 xCaxGa2S4 : Ce,Na can be used as blue emitting phosphors pumped by the violetLED for fabricating the multi-band white LED.
