| 摘 要： | 用CaCO3(A.R.),SiO2(4N),Mg(NO3)2·6H2O(A.R.),CaCl2(A.R.)和Eu2O3(4N)为原料,经高温固相反应,得到了新荧光体Ca8-xMg(SiO4)4Cl2:Eux2+.对该荧光体的晶体结构和荧光光谱进行分析发现:该荧光体可能为单中心发光,Eu2+主要占据对称性为C2的CaⅡ格位.

| Abstract: | Using CaCO3, Mg(NO3)2·6H2O, CaCl2, SiO2 and Eu2O3 as raw materials, a new Eu2+-doped phosphor Ca8-xMg(SiO4)4Cl2:Eu2+ has been synthesized by high temperature solid phase reaction. Its crystal structure and fluorescence spectra show that the phosphor has single luminescent center and Eu2+ ion mainly occupies the site CaⅡ with the symmetry C2. |
