Abstract

Polyvinyl alcohol (PVA) polymer, methyl orange (MO) and their composite was dissolved in water in order to prepare films with different thickness by casting method. The films were irradiated by a violet laser with a wavelength 405 nm for different times (0, 10, 20, 30 and 40) minute. The dispersion parameters were calculated before and after exposure to the laser using the Wemple–DiDomenico method. Dispersion energy (E _d) and the single oscillator energy of electronic transition (E _o) were increased with increasing the irradiating time for PVA, MO and PVA/MO thick films. This is useful to modify geometrical and optical specifications for materials which has many applications especially in the medical field. The Urbach energy also can be controlled by the irradiation times since it decreased with increasing the laser irradiation time which can be used to enhance the structure of the material.

紫激光辐照对 PVA/MO 复合厚材分散特性的影响

将聚乙烯醇（PVA）聚合物、甲基橙（MO）和它们的复合材料溶于水，用浇铸法制备不同厚度的薄膜。用波长为 405 nm 的紫激光照射薄膜不同的时间（0、10、20、30 和 40 分钟）。使用 Wemple-DiDomenico 方法计算了激光照射前后的分散参数。PVA、MO 和 PVA/MO 厚膜的色散能（Ed）和电子转变的单振荡能（Eo）随着照射时间的增加而增加。这有助于改变材料的几何和光学规格，尤其是在医疗领域的应用。Urbach 能量也可以通过辐照时间来控制，因为它随着激光辐照时间的增加而降低，这可用于增强材料的结构。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
