Abstract
A novel red-emitting phosphor Sr2La8(SiO4)6O2:Eu3+ was synthesized by high-temperature solid-state reaction method. X-ray powder diffraction (XRD) analysis confirmed the formation of Sr2La8(SiO4)6O2:Eu3+ phase. The photoluminescence excitation (PLE) and emission (PL) spectra show that the phosphor can be efficiently excited by near ultraviolet (NUV) and blue light, and emits red light. The phosphor demonstrates much higher quantum efficiency, and its color coordinates lie in the red region. All results in the present work suggest that the prepared phosphors have potential application as red emitting phosphors for near ultraviolet white light emitting diodes (NUV WLEDs).
