摘　　要：采用化学溶液沉积法制备了Cs_(2)LiBiCl_(6):Mn^(2+)(x=0.01~0.3)系列新型橙黄色荧光粉。通过X射线衍射(XRD)和荧光光谱仪(PLE/PL)等手段对荧光粉的结构和发光性能的进行表征。结果表明:所得到的Cs_(2)LiBiCl_(6):Mn^(2+)系列样品为立方相晶体结构,能被近紫外/蓝光(250~470nm)有效激发,最强发射波长位于607nm处,随着Mn^(2+)离子浓度增加,该荧光粉的色坐标从黄光区域(0.506,0.480)移动到橙黄光区域(0.590,0.409),是一种具有潜在应用前景的白光LED用新型橙黄色荧光材料。A series of novel orange-yellow phosphors Cs_(2)LiBiCl_(6):Mn^(2+)(x=0.01~0.3)were prepared by chemical solution method.The samples of the structure,morphology and luminescence properties of phosphors were characterized by X-ray diffraction(XRD)and fluorescence spectrometer(PLE/PL).The results show that the obtained A series of Cs_(2)LiBiCl_(6):Mn^(2+) have a cubic crystal structure.These phosphors can be effectively excited by near-ul-traviolet/blue light(250~470 nm),emitting the maxium line at 607 nm,with the Mn^(2+) ion concentration increases,the color coordinates of the phosphor move from the yellow light area(0.506,0.480)to the orange light area(0.590,0.409),which was a new orange-yellow fluorescent material for white light LED with potential application prospects.a novel orange-yellow fluorescent material for white LEDs with potential application prospects.
