摘要: 为寻找高性能荧光温敏探针材料,用荧光强度比率法,对NaY9-x-y(SiO4)6O2:xBi3+,yEu3+荧光粉体的温敏特性进行了研究.结果表明:该材料中存在Bi3+→ Eu3+的高效能量传递,单一波段激发Bi3+发光离子,可获得Bi3+和Eu3+的双发射荧光光谱;温度升高时,Eu3+发射光谱的猝灭速率比Bi3+缓慢;根据不同温度下2种发光光谱强度的比值,获得了NaY6.192(SiO4)6O2:0.108Bi3+,2.7Eu3+在300~450 K最高相对灵敏度为1.51 %·K-1,大大优于可实用温敏材料的相对灵敏度数值(0.3 %·K-1),该材料具有较大的实际应用前景.

Abstract: To search probe phosphors with better performance temperature, using the ratio method of the fluorescence intensity, the thermosensitive performance of the NaY9-x-y(SiO4)6O2:xBi3+,yEu3+ phosphor has been studied. The results show the efficient energy transfer from Bi3+ to Eu3+ can be observed. With the excitation of Bi3+, the double emission spectra of Bi3+ and Eu3+ can be acquired. With the increase of the temperature, the fluorescence intensity quenching speed of Eu3+ is slower than that of Bi3+. Based on the temperature dependent fluorescence intensity ratio of Bi3+ to Eu3+, the relative sensitivity(Sr)values of the NaY6.192(SiO4)6O2:0.108Bi3+,2.7Eu3+ probe phosphor at the temperature range of 300 to 450 K have been calculated. The maximum(Sr)is 1.51 %·K-1, which is much better than the suggested value of 0.3 %·K-1 for the practical applications. The temperature probe phosphor in this work showed the potential in the temperature sensitivity fields.
