【摘要】 用准分子脉冲激光沉积法(PLD)制备了一系列的锌、铁,钛、银、铝、硅、铜等的氧化物单层和多层薄膜,用AFM研究了薄膜的组成和结构;经紫外和红外光谱发现:抗紫外性能最好的是氧化锌,在190-380nm区间,其吸收率可达90%以上。抗近红外性能最好的是氧化银薄膜,其次依次是氧化铁、氧化锌、氧化钛、氧化铝、氧化铜;多层薄膜中,含有氧化锌层的抗紫外效果最好;含有氧化银层的抗近红外性能效果最好。如氧化铁/氧化锌/氧化银薄膜,在190-380nm区间,其吸收率接近100%,近红外(780-2500nm)吸收率在70%以上,最高可达90%。在可见先区其透过率在80%左右。更多还原

【Abstract】 A series monolayer and multi-layers films of zinc, iron, titanium, silver, aluminum, silicon and copper oxides were prepared through the method of pulsed laser deposition (PLD). Their composition and structure were studied by AFM. According to Uv-vis and IR spectra, for monolayer films, in ultraviolet ranging from 190nm to 400nm, zinc oxide can absorb above 90%. Silver oxide film possesses the best property of anti-infrared .As to multi-layers films; those containing zinc oxide still have the best effect on anti- ultraviolet. And the same rules are suitable for silver oxide on anti-infrared. Take iron/zinc/silver oxide film for example, the absorptive approaches to 100% at the range of 190-380nm and 70% to the tiptop 90% for near infrared (780-2500nm). Besides, its transmittance in visible light region can reach about 80%.更多还原
