摘要：

采用高温固相法制备了系列荧光粉Ba2B2O5:Ce3+, Mn2+，研究了材料的发光性能。结果表明：Ba2B2O5:Ce3+, Mn2+在250～400 nm范围内有较强的吸收，且Ce3+到Mn2+存在能量传递，当Mn2+掺杂量合适时，材料发射白色光。Ce3+到Mn2+的能量传递机理为电偶极–电偶极相互作用，利用浓度猝灭方法计算得到了能量传递的临界距离为1.33 nm。测得Ba2B2O5:0.03Ce3+, 0.07Mn2+的色坐标为(0.309, 0.292)，色温为6 036 K。当测试温度为150 ℃时，材料的发射强度仍可以保持为室温时的80.0%。表明Ba2B2O5:Ce3+, Mn2+在紫外基白光LEDs领域有一定的潜在应用价值。
