摘要
采用溶胶-凝胶(Sol-Gel)技术在(100)Si及石英衬底上制备了Ba0.95Pb0.05TiO3(BPT)铁电薄膜。利用X射线衍射(XRD)、原子力显微术(AFM)对薄膜的物相结构、结晶性和表面形貌进行表征,结果表明晶化完整的BPT薄膜呈多晶钙钛矿结构,薄膜表面均匀致密.用紫外-可见分光光度计在190～1000nm波长范围内,测量了不同温度退火的BPT薄膜的光学透射率,并通过透射光谱计算了薄膜折射率和消光系数的色散关系.
Ba_(0.95) Pb_(0.05)TiO_3(BPT)thin films were grown on (100)Si and fused quartz substrates by sol-gel process. XRD and AFM were used to investigate the crystallite and surface of the films,the results show that BPT thin films have a perovskite phase structure. The films were homogeneous and crack-free. The optical transmission spectra of BPT thin films were measured in the wavelength range 190～1 000 nm.The refractive index and extinction coefficient as the function of wavelength were calculated through the optical transmission spectra.
