More Information
Summary:A phosphor which contains Cr < 3 + > and emits near-infrared light, the parent crystal of the phosphor having the same crystal structure as the compound Mg3Ga2GeO8, and the fluorescence spectrum FF1 having a fluorescence peak FPF1 in the wavelength range of 700 nm or more and less than 900 nm, a fluorescence spectrum data set (FD), which is an aggregate of spectral intensity per 10 nm of the fluorescence spectrum (FF1), exhibits a unimodal pattern in a wavelength range of 700 nm or more and less than 900 nm. 一种荧光体，其是含有Cr3+并发出近红外光的荧光体，荧光体的母体晶体具有与化合物Mg3Ga2GeO8相同的晶体结构，荧光光谱FF1在波长700nm以上且小于900nm的范围内具有荧光峰FPF1，所述荧光光谱FF1的每10nm的分光强度的集合体即荧光光谱数据组FD在波长700nm以上且小于900nm的范围内呈现单峰型。
