摘　　要：采用溶胶-凝胶法制备了LED用Ca_6Sr_4(Si_2O_7)_3Cl_2:Ce^(3+),Eu^(2+),Sm^(3+)白色荧光粉。探讨了Ba^(2+),Mg^(2+)的加入对其发光性能的影响。结果表明:Ba^(2+),Mg^(2+)能很大程度上的提高荧光粉的发光强度,两种离子的最佳掺杂浓度分别为0.20和0.1,随着加入量的增加样品发光强度先增大后减小。In this paper,it has adopted the sol-gel method to prepare Ca6Sr4(Si2O7)3Cl2:Ce3+,Eu2+,Sm3+White Fluorescent Powder for LED and discussed the influence of Ba2+amd Mg2+adding on its luminescence property.The result has shown that the Ba2+and Mg2+has increased the luminous intensity of high fluorescent powder to a large extent and the optimum dosage concentration is respectively0.20and0.1,besides,along with the increase of added quantity,the sample luminous intensity has increased firstly and decreased later.
