)TiO

薄膜

研究了不同退火温度下样品的物相结构、薄膜的光致发光性能和光学透过率。结果表明:室温下非晶钛酸锶钡薄膜在蓝光激发下具有明显的发光现象

发光波长范围是500~650nm

峰值在525nm附近。延长非晶态薄膜的退火时间能够显著提高样品的发光强度

且发光强度随薄膜厚度增加而增大。晶态薄膜有微弱的发光现象。透射谱测试结果表明

钛酸锶钡薄膜在可见光范围内具有良好的光学透过率。

)TiO

thin film was prepared by sol-gel process.The phase structure

photoluminescence properties and optical transmittance of the films annealed at different temperature were studied respectively.The results show that a strong photoluminescence phenomenon can be observed under blue light excited at room temperature.The emission band is from 500 nm to 650 nm

and the peak is about 525 nm.An enhanced intensity of photoluminescence property was measured by increasing the anneal time for amorphous films.Moreover

the photoluminescence intensity also increases with the film thickness.A weak photoluminescence peak was observed in crystalline film.In addition

both the crystalline and amorphous films have good optical transmittance in the visible light region.
