Bi,Eu co-doped SrLuO phosphors were synthesized by a solid state reaction method. Their structural, luminescent and temperature sensing properties have been systematically investigated. The color-tunable emissions from violet to red were detected with the increase of Eu concentration. Relying on energy transfer process from Bi to Eu and thermal quenching behaviour, the fluorescence intensity ratio (FIR) presents excellent temperature sensing performance. The maximum absolute and relative sensitivities reach 1.10% K and 0.87% K, respectively. These meaningful results indicate that SrLuO:Bi,Eu is a promising material for optical temperature sensing.
通过固相反应法合成了Bi、Eu共掺杂的SrLuO荧光粉。对其结构、发光和温度传感性能进行了系统研究。随着Eu浓度的增加，检测到从紫色到红色的颜色可调发射。基于从Bi到Eu的能量转移过程和热猝灭行为，荧光强度比（FIR）呈现出优异的温度传感性能。最大绝对灵敏度和相对灵敏度分别达到1.10% K和0.87% K。这些有意义的结果表明，SrLuO:Bi,Eu是一种有前途的光学温度传感材料。
