摘 要:航空发动机热端部件表面温度的精确测试对发动机的设计及研发至关重要。采用溶胶凝胶法制备了YSZ∶Er^3+荧光粉,用于航空发动机涡轮叶片表面温度分布测试。采用XRD对YSZ∶Er^3+样品进行了物相分析,采用980 nm氙灯作为激光源,测试了900,950和1000℃下热处理15 min的YSZ∶Er^3+样品的上转换荧光发光光谱和荧光寿命。结果表明,随着温度的升高,YSZ∶Er^3+样品的荧光发射峰强度迅速增大,其中547 nm处发射峰强度对温度最为敏感;同时,样品的荧光寿命也随热处理温度线性上升。结合YSZ∶Er^3+的荧光发光强度和荧光寿命的变化测试热历史温度,可以进一步提高测温精度。Precise surface temperature measurement of the aero-engine hot components is crucial for the design and development of the engine.The YSZ∶Er^3+phosphor was prepared by the sol-gel method,which could be used to measure the surface temperature distribution of the turbine blades.The phase of YSZ∶Er^3+samples were analyzed with XRD after 900℃,950℃and 1000℃heating treatment for 15 min,respectively.And the up-conversion fluorescence emission spectrum and fluorescence lifetime of the YSZ∶Er^3+samples were measured with the 980 nm xenon lamp as the laser source.The results show that with increasing heat treatment temperature,the intensity of fluorescence emission peaks of the YSZ∶Er^3+samples increases rapidly,the intensity of the peak at 547 nm is most sensitive to the temperature.The fluorescence lifetime also increases linearly with increasing temperature.Taken the fluorescence luminescence intensity and the fluorescence lifetime variations of YSZ∶Er^3+together,the precision of temperature measurement can be further improved.
关 键 词:YSZ∶Er^3+ 溶胶凝胶 发射峰强度 荧光寿命 温度传感器
