STRUCTURAL, ELECTRONIC STATE CHARACTERIZATION AND PROPERTIES OF COATED TiO2 NANOPARTICLES
【摘要】 报道用微乳液法制备TiO2纳米微粒的过程和条件,并对纳米微粒的结构、形貌等进行了表征,分析了量子尺寸效应对它的光吸收的影响,并对其光学非线性进行了初步研究。
【Abstract】 In this paper the microemulsion preparation, the morphology and structural characteristics of toil nanoparticles are reported in detail. The quantum confinement effect upon the strong polarizable nanoparticle are described with interfacial polarization, and their linear and nonlinear optical absorp-tion responses are explained with self trapped exciton model.
