摘要
采用溶胶-凝胶法制备了系列Ba2MgSiO5:Eu^2+发光材料,并采用X射线衍射仪(XRD)、荧光光谱(PL)等测试方法对样品的物相结构和发光特性进行了表征及测试。研究结果表明:Ba2MgSiO5:Eu^2+发光材料中,加入少量Eu^2+离子后没有明显改变Ba2MgSiO5晶体结构。确定了晶化时间=1 h,Eu^2+的最佳掺杂量为摩尔分数x(Eu^2+)=0.05,Ba2MgSiO5:Eu^2+发光强度最佳。
The luminescent materials of Ba2MgSiO5:Eu^2+were prepared by sol-gel method,and the resultant samples were characterized and analyzed using X-ray diffraction(XRD)and fluorescence spectroscopy(PL).The results showed that the addition of a small amount of Eu^2+ions did not significantly change Ba2MgSiO5 crystal structure in the Ba2MgSiO5:Eu^2+luminescent material.It was determined that the crystallization time was 1 h,the best doping amount of Eu^2+molar fraction x(Eu^2+)=0.05,Ba2MgSiO5:Eu^2+had the best luminous intensity.
