摘要/Abstract

摘要： 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.

关键词: 菁染料薄膜, 溶剂效应, AFM

Abstract: In CD R optical disc,the recording media film should have nice optical properties in order to depress reading noise and increase the reliability when data are processed.Cyanine dyes are one of the most popular recording media.When the cyanine dye was spin coated in this experiment,it was found that the solvents had great influence on the dye film.The observation on the film surface with AFM indicated that the reflectance was closely related to the roughness of film.Dye films were flat and had high reflectance when cholroform,tetrafluoro propanol or diacetone alcohol were used as the solvent,respectively.When the solvent was methanol,many mirco crystals sized 0.3 μm were found in the dye film,which had great scattering effect on the light and resulted in the decrease of the light reflectance.

Key words: cyanine dye film, solvent effect, AFM
