摘要:

采用高温固相法合成了NaBaPOM4:Tb3+绿色荧光粉, 并研究了材料的发光性质. NaBaPOM4:Tb3+材料呈多峰发射, 发射峰位于437、490、543、587和624 nm, 分别对应Tb3+5D37F45D47FJ=6, 5, 4, 3跃迁发射, 主峰为543 nm; 监测543 nm发射峰, 所得激发光谱由4f75d1宽带吸收(200-330 nm)和4f-4f 电子吸收(330-400 nm)组成, 主峰为380 nm. 研究了Tb3+掺杂浓度, 电荷补偿剂Li+、Na+、K+和Cl-, 及敏化剂Ce3+对NaBaPOM4:Tb3+材料发射强度的影响. 结果显示: 调节激活剂浓度、添加电荷补偿剂或敏化剂均可以在很大程度上提高材料的发射强度.

Abstract:

We synthesized a kind of green phosphor, NaBaPOM4:Tb3+, by the high temperature solid-state method, and investigated its luminescent characteristics. NaBaPO4:Tb3+ has several emission peaks, and these are located at 437, 490, 543, 587, and 624 nm, which correspond to the 5D37D4 and 5D47FJ=6. 5, 4, 3 transitions of Tb3+, respectively. The main peak is at 543 nm. The excitation spectrum (monitored at an emission wavelength of 543 nm) consists of several bands, and the main peak is located at 380 nm. The effect of amount of Tb3+ doping content, the compensators (Li+, Na+, K+, or Cl-), and the sensitizer activator Ce3+ on the emission intensity of the NaBaPOM4:Tb3+ phosphor were also studied. The results show that the emission intensity can be controlled by the above factors, and the intensity can be enhanced by selecting the prime optimum conditions.
