A New Deep Red-Emitting Mn2+-Activated SrLaGa3S6O Phosphor

摘要：

　　A new deep red-emitting Mn2+-activated SrLaGa3S6O phosphor was first prepared by a solid-state reaction method.Their luminescence properties were investigated by photoluminescence excitation and emission spectra.The emission spectrum shows a broad band with an emission maximum at 668 nm under the host excitation of 340 nm.The full width at half maximum (FWHM) of the emission peak is about 83 nm.The CIE chromaticity coordinates (x =0.673 and y =0.312) shows that the phosphor emission is in the deep red region and were very near to the NTSC standard values for red.Since the excitation band of the phosphor lies in the near UV excitable region,giving a deep red emission,it can be used for applications in near UV phosphor converted white LED lighting and display devices.
