Abstract
series of Ca1-xSrxS:Ce phosphors were synthesized by solid-state reactions. The Ca1-xSrxS:Ce phosphors have a strong absorption in region from 430 nm to 470 nm. The emission peaks of CaS:Ce are located at 510 nm and 570 nm. The partial replacement of Ca by Sr in Ca1-xSrxS:Ce causes a blue shift of emission wavelengths. The Ca1-xSrxS:Ce can be used as bluish green and yellow emitting phosphors for white light emitting diodes (LEDs) pumped by the blue LED. We reported the optical properties of Ca1-xSrxS:Ce phosphors for application in phosphor converted white LEDs.
