Technology for Preparing Organic Dye Film onto Gel Substrate

By adopting Sol-Gel technology and spin-coating method, the organic dye film doped with cations was prepared onto gel substrate placing on glass plate. The defects of film during the process of film preparation were analysed and studied in detail. The results indicated that the constituent proportion of sol and coating parameter and drying and heat treatment of gel are the principal factors causing the defects. By adjusting the proportioning of precursory constituent and controlling coating parameter and drying process and temperature, the authors had obtained the organic dye film with good optical quality. Characterization of the optical property of this film was conducted with the help of high resolution EMS and UV visible absorption spectrum and some other means of analysis and measurement.
