A large amount of nano - crystals are found in the film when the sample was annealed for one hour at 500 ? with the crystallinity being increased to 50 % 研究结果发现，未经过退火处理的薄膜是纳米晶粒镶嵌于非晶介质的复合薄膜，薄膜中的结晶程度不是很高。

The photoluminescence of the thin films without post heating shows that the increasing of the deposit temperature decreases the pl intensity . only the sample deposited at 450 has one evident luminescence band found nearby 523 . 2nm 对复合镶嵌薄膜光致发光特性的研究发现，在450沉积未经过退火处理的薄膜样品中观察到室温光致发光现象，在523 . 2nm附近有一强的发光谱带。
