摘    要:采用高温固相法合成了Ca3(PO4)2:RE3+(RE = Eu, Dy, Ce, Tb)系列发光材料,研究了其发光性质。研究表明Ca3(PO4)2: RE3+ 在紫外区域均能有效被激发,有很强的荧光发射,且发光范围覆盖蓝到红光波段,是一类可以紫外激发实现白光LED用的潜在荧光粉。在0.005到0.03 mol 浓度范围内,Eu,Dy和Ce掺杂的荧光粉的发光都发生了浓度淬灭,分别对应于0.025,0.025和0.02 mol,而Tb3+掺杂的样品的表现出高的发光淬灭浓度。

关 键 词:材料  荧光粉  高温固相法  磷酸盐基质  白光LED

Abstract:A series of phosphors Ca3(1-x)(PO4)2: xRE3+(RE = Eu, Dy, Ce, Tb) have been prepared by a high temperature solid-state reaction method. Their luminescence properties were investigated. The results indicated that all samples could be effectively excited by ultraviolet light with the range from blue to red light, and they are the potential phosphors to obtain white LED excited by ultraviolet light.In the range of 0.005 to 0.03 mol, photoluminescence quenching concentration of Eu3+, Dy3+, and Ce3+-doped are 0.025, 0.025, and 0.02 mol, respectively, and Tb3+-doped samples has high quenching concentration.
Keywords:materials  phosphor  high temperature solid-state reaction  phosphate substrate  white LED
