(Pb_(1-x)Sr_x)TiO_3薄膜的结构与光学特性研究
Structure and optical properties of (Pb_(1-x)Sr_x)TiO_3 thin films
摘要
Abstract
Lead strontium titanate (Pb_(1-x)Sr_x)TiO_3 (x=0.40, 0.50, 0.60 and 0.70, abbreviated as PST40, PST50, PST60 and PST70, respectively) thin films were deposited on fused quartz substrates using a sol-gel method with spin-coating processing. The structure and optical properties of PST thin films were studied. The results show that the all samples are perovskite cubic structure when the PST thin films are annealed at 750 ℃ for 30 min. Its average grain size is 200～300 nm. The direct band gap energies are 3.74, 3.79, 3.80, and 3.85 eV, respectively for PST40, PST50,PST60 and PST70 thin films annealed at 750 ℃. The band energies are increased with increasing content of strontium.关键词
