摘要：纳米硅与纳米氧化锌复合材料的光学特性研究。用多孔硅衬底上生长ZnO薄膜的方法来制备复合材料。首先用化学腐蚀法制备多孔硅衬底，制备过程中要注意溶液的浓度和腐蚀时间的控制。制成多孔硅后进行形貌特征分析。然后采取了在多孔硅上旋涂胶体煅烧制成纳米ZnO薄膜。用溶胶凝胶法以乙酸锌为主要原料来配置制备ZnO的胶体。复合材料制成后研究它的光学特性，我们主要研究多孔硅上生长ZnO薄膜的发射光谱。通过复合材料的发射发光光谱研究纳米硅与纳米氧化锌复合材料的光学性能。

Abstract:Optical properties of nanometer silicon with nano-zinc oxide composites research, Preparation of composite with ZnO thin films grown on porous silicon substrate. first, using chemical corrosion method to make the porous silicon substrate ,which pay attention to the concentration of the solution and corrosion control during preparation process. Then analyzing the morphology of the porous silicon . And then take a coating on a porous silicon body calcined made of nano - ZnO thin films. Zinc acetate as the main raw material for preparation of ZnO colloidal by sol-gel method . after that Studying the optical properties of composite materials.We mainly studied the emission spectrum of ZnO thin films grown on porous silicon.It researched optical properties of nano silicon and nano-zinc oxide composite materials by the emission spectrum spectrum of the composite material .
Keywords: Porous silicon Sol-gel ZnO thin films Emission spectrum Composite materials Optical properties
