本文研究介质薄膜的各种特性:折射率和吸收系数、光散射、结构、显微结构、密度、气体吸收、化学成分、均匀度、附着力、硬度和机械应力、环境影响。Ⅰ、前言适当地选择折射率、薄膜厚度和膜层数目,可以设计出各种通常是很复杂的光学薄膜,这种薄膜设计,要在工业上得以实现,是需要足够数量的高质量镀膜材料,经过处理之后,使薄膜有适当的复现特性。尽管在过去几年中材料科学和镀膜技术有显著的进展,但遗憾的是适合的材料数目仍然有限。单层薄膜的主要介质材料的基本光学性质的研究是 Hass
In this paper, various properties of dielectric thin films are investigated: refractive index and absorption coefficient, light scattering, structure, microstructure, density, gas absorption, chemical composition, uniformity, adhesion, hardness and mechanical stress, and environmental impact. I. INTRODUCTION Proper choice of refractive index, film thickness and number of layers allows for the design of a wide variety of generally complex optical films. This film design, which is commercially available, requires a sufficient number of high quality coating materials , After treatment, the film has the appropriate reproduction characteristics. Despite significant advances in materials science and coating technology over the past few years, it is regrettable that the number of suitable materials is still limited. The basic optical properties of the major dielectric materials for monolayers are Hass
