摘　　要：以BaCO_3、SrCO_3、TiO_2和Eu_2O_3为原料,采用高温固相法制备了不同浓度的Eu^(3+)掺杂的Ba(0.8-x)Sr_(0.2)TiO_3∶xEu^(3+)(x=0.02~0.1)系列红色荧光粉。采用荧光分光光度计对其发光强度和吸收强度进行研究得出,最佳的Eu^(3+)摩尔分数x=0.08。考察了不同电荷补偿剂对Ba_(0.72)Sr_(0.2)TiO_3∶0.08Eu^(3+)荧光粉激发光谱和发射光谱的影响,结果表明,Li+是制备Ba_(0.72)Sr_(0.2)TiO_3∶0.08Eu^(3+)荧光粉的最佳电荷补偿剂。Red phosphors Ba_（（0.8-x））Sr_（0.2）TiO_3∶xEu3＋（x=0.02～0.1）were prepared by a conventional solid-state reaction method using stoichiometric amounts of BaCO_3,SrCO_3,TiO_2 and Eu_2O_3 as raw materials.Used spectrophotometer to test the luminescent intensity and absorption intensity of it.And the best concentration of Eu3＋was x=0.08.The effect of different charge compensators on excitation spectra and emission spectra of phosphor was also discussed.The results showed that Li＋was the best charge compensator for preparing the phosphor.
