利用溶胶凝胶法在玻璃衬底上制备了金-二氧化钛（Au-TiO2）复合纳米薄膜,研究了热处理温度对复合薄膜表面纳米颗粒沉积的影响。利用原子力显微镜对样品进行了形貌表征,结果显示：复合薄膜是由纳米微晶组成的致密膜,温度越高越有利于Au粒子的形成。在550℃的热处理温度下,薄膜表面沉积的纳米微晶的粒径约为100nm。利用紫外-可见分光光度计测量了反射谱线,结果表明：由于局域表面等离子体共振（LSPR）的产生,在不同的热处理温度下,第一个反射峰（短波长处）不发生变化,第二个反射峰（长波长处）发生漂移（红移）。

Gold nanoparticles embedded titanium dioxide（TiO2） thin film was fabricated through sol-gel method.Effect of the annealing temperature on the property of the composite film was studied by AFM characterization.The results show that the higher temperature is good for the generation of the Au.The reflection spectrum was measured by ultraviolet visible spectrophotometer,reflection dip evolves into two separate branches which is due to the enhanced absorption because of the localized surface plasmon resonance（LSPR）.
