摘要

采用高温固相法制备了Ca1.9(Si.0.8P0.2)O4∶Re(Re=Eu2+

Eu3+)系列发光材料，并对光致发光性能的影响因素进行了探究，主要包括煅烧温度、煅烧时间、稀土离子掺杂浓度等。经表征分析可知，制备Ca1.9(Si0.8P0.2)O4∶Eu2+ 样品工艺条件确定为：煅烧温度、时间及掺杂Eu2+浓度分别为1.275℃、4h及4%。此样品最强激发波长为374nm，最强发射波长为500nm。色坐标结果显示样品发光处于绿光区域。制备Ca1.9(Si0.8P0.2)O4∶Eu3+ 样品工艺条件确定为：煅烧温度、时间及掺杂Eu3+浓度分别为1300℃、4h及6%。此样品最强激发波为394nm，最强发射波长为589nm。色坐标结果显示样品发光处于红光区域。

Abstract

The Ca1.9(Si0.8P0.2)O4∶Re(Re=Eu2+

Eu3+)powders were prepared by high temperature solid state reaction method. Thefactors affecting the photoluminescence properties were systematicallyinvestigated

which including calcination temperature

calcination time anddoping concentration of rare earth ions.The characterization analysis showedthat the preparation conditions of Ca1.9(Si0.8P0.2)O4∶Eu2+weredetermined as follows: calcination temperature

time and doped Eu2+concentration were 1275℃

4h and 4%

respectively. TheMaximum excitation wavelength of this sample was 374nm

and the maximumemission wavelength was 500nm. The emitting color of Ca1.9(Si0.8P0.2)O4∶Eu2+was green. Theprocess conditions of preparing Ca1.9(Si0.8P0.2)O4∶Eu3+were determined as follows: calcination temperature

calcination time andconcentration of doped Eu2+ were 1300℃

4h and 6%

respectively. The Maximum excitation wavelength ofthis sample was 394nm

and the maximum emission wavelength was 589nm. Theemitting color of Ca1.9(Si0.8P0.2) O4∶Eu3+ wasred.
