摘    要:采用阳极腐蚀法制备了多孔硅(PS),用原子力显微镜(AFM)照片对其表面和结构做了分析,观察到多孔硅纳米尺寸的微结构;并进行了多孔硅层(PSL)的光致发光谱(PL)测量,观察到PL谱峰的“蓝移”和双峰现象,符合量子尺寸效应和发光中心理论,红外吸收光谱进一步证明了发光中心的存在。

关 键 词:多孔硅  红外吸收谱  量子效应  蓝移  微结构  荧光光谱  双峰结构

Abstract:In this article, a porous silicon was fabricated by electrochemical anodizing using our self-designed apparatus, and its surface morphology was observed with an atomic force microscope. From the photoluminescence spectra of porous silicon layers, the phenomenon of blue shift and double peaks can be seen. It was concluded that the quantum confinement theory and luminescence centers were responsible for these phenomena.. The Infrared Spectrum proves the existence of luminescence centers.
Keywords:Porous Silicon (PS)  Infrared Absorption Spectra (IR)  quantum confinement theory  blue shift
