Abstract

The phosphors SrS: Eu and CaS: Eu doped with Mn were prepared by sulfurization flux method (SFM). Infrared photostimulated luminescence (PSL) of both the phosphors were measured. The PSL peak wavelength of SrS: Eu, Mn is 610 nm. Comparing the storage intensities, SrS has better optical properties. The doping of Mn2+ increases photon amount and improves the storage properties.

摘要

采用硫化助熔剂法（SFM）制备了掺杂Mn的磷光体SrS:Eu和CaS:Eu。测量了这两种磷光体的红外光激励发光（PSL）。SrS:Eu,Mn的PSL峰值波长为610nm。比较存储强度，SrS具有更好的光学性能。Mn2+的掺杂增加了光子数量并改善了存储性能。
