摘要

针对温度传感应用研究了(Ba,Sr)2SiO4∶Eu2+绿色荧光粉荧光光谱的温度特性。在波长405 nm 激光的激发下，将样品从室温加热到185 ℃，在该温度区间内每间隔10 ℃记录其稳态发射光谱。使用两种新型传感方法，发射谱带的重心波数位置和不同波长的发射强度比,得出对应的温度传感方程,并与峰值波长位置随温度的频移变化以及随温度升高发射谱带的展宽情况作了对比分析和讨论，对各温度传感机制和精度作了简要比较、讨论。结果表明，该荧光粉具有多种优秀的点温度传感能力，尤其两种新型温度传感方法具有良好的实用性且与已有传感方法很好地兼容，该荧光材料作为温度敏感材料有较好的应用前景。

Abstract

The steady-state temperature-dependent fluorescence of (Ba,Sr)2SiO4∶Eu2+ is studied, under an excitation at 405 nm. After the raise of two novel sensing methods, barycenter technique and intensity ratio technique for wide band emissions, multiple sensing functions are retrieved, using the behaviors of wavenumber/wavelength of emission band barycenter, emission bandwidth, and ratios of intensities at different wavelengths in the emission band, respectively. All the four kinds of functions demonstrate nearly linear relationship with temperature in the measurement range. The sensing mechanisms are briefly discussed. The phosphor′s multi-functional temperaturesensing abilities can be taken advantages of for use as a point thermometer for a variety of applications.
