在CD R光盘中 ,要求记录介质薄膜有良好的光学性能 ,这样才能降低噪音 ,提高数据存储与读取的可靠性 .菁染料是应用最广泛的记录介质 ,本文采用旋涂法制备菁染料薄膜时 ,发现溶剂对薄膜的光学性能有很大的影响 .通过AFM对薄膜表面的微观精细结构的研究表明 ,染料薄膜反射率的高低与薄膜表面粗糙度有关 .其中使用氯仿、四氟丙醇和二丙酮醇作溶剂时 ,制备的染料薄膜表面平整 ,反射率较高 ;使用甲醇作溶剂时 ,染料薄膜布满直径 0 .3μm左右的晶粒 ,对光线有强烈散射作用 ,从而降低了染料薄膜的光学性能
In CD R discs, recording medium film is required to have good optical properties, so as to reduce noise and improve the reliability of data storage and reading.Cyanocyanine is the most widely used recording media, this paper uses spin-coating method to prepare cyanine dye film , It was found that the solvent has a great influence on the optical properties of the film.Studies on the microscopic fine structure of the film surface by AFM showed that the reflectivity of the dye film was related to the film surface roughness.Using chloroform, tetrafluoropropanol and bis Acetone alcohol as a solvent, the prepared dye film surface smooth, high reflectivity; the use of methanol as a solvent, the dye film covered with crystal particles with a diameter of about 0. 3μm, a strong scattering of light, thereby reducing the dye film Optical performance
