温度对非晶SiO_x薄膜的光致发光特性的影响
The influence of temperature on photoluminescence of SiO_x films
【摘要】 采用双离子束共溅射法制备的SiOx 薄膜为非晶结构 ,在室温下观察到了可见光致发光 (PL)现象 ,探测到样品有四个PL峰 ,它们的峰位分别为~ 32 0nm ,~ 4 10nm ,~5 6 0nm和~ 6 30nm ,且峰位和峰强随温度 (基片温度Ts 和退火温度Ta)的变化而发生变化 ,并对实验结果进行了讨论
【Abstract】 The SiO x films were prepared by a dual ion beam co sputtering method from a composite target in argon atmosphere.The structure of the films studied by the aid of TEM and XRD is amorphous.The photoluminescence (PL) spectra were found to have 4 luminescent band peak at 320nm,410nm,560nmand 630nm,respectively,at room temperature,and analyze the PL mechanism.
