摘要
制备了用于宽频谱红外上转换的SrS:Eu,Sm荧光粉。XRD分析表明,在1100℃,灼烧1h 获得的SrS:Eu,Sm样品较理想,为SrS的面心立方结构;激发光谱表明,样品可被紫外和可见光有效激发;样品的荧光发射光谱由4个发射峰组成,峰值分别位于567,589,602和648 nm。红外上转换发光光谱是峰值位于595 nm附近的宽带谱,样品的红外响应范围主要位于800-1400 nm。
Abstract
In the present paper,SrS:Eu,Sm phosphors for the broad frequency infrared up-conversion were prepared.XRD analysis indicates that the SrS:Eu,Sm samples calcined at 1 100 ℃ for 1 h exhibit good luminescence properties and they are face-center cubic structure of SrS.Excitation spectrum reveals that the samples can be excited by ultra violet and visible light.Fluorescence spectrum of the samples is composed of four emission peaks at 567 nm,589 nm,602 nm and 648 nm respectively.Infrared photo-stimulation luminescence spectrum is a broad-band spectrum peaking at about 595 nm.Infrared response range of the samples is mainly between 800 and 1 400 nm.
