摘要
分别采用电阻热蒸发和电子束热蒸发的方法 ,在石英基底上制备了十几种用于紫外光区的氧化物和氟化物单层膜 ,通过测其在 2 0 0～ 2 0 0 0nm波段内的透射率 ,计算出了这些膜材料在从紫外到红外波段内的折射率n和消光系数k的色散曲线 。
Some single-layer films of different materials used in the ultraviolet region, which include oxide and fluoride, have been made on the fused silica substrate by resistive heating evaporation or electron beam bombardment technique. According to their transmissivity in 200-2000 nm, dispersion curves of these materials refractive index and extinction coefficient are obtained. Then their band gap through Tauc plot method and cut-off wavelengths are got.
