Abstract

Abstract: Two indodicarbocyanine and indotricarbocyanine dyes were synthesized. The structure of dyes were confirmed by elemental analysis, IR and ¹H NMR measurements. The film medium containing cyanine dye and polymer on a substrate were perpared by spin coating process. Both of the optical absorption spectra and optical constants of the film were investigated. At optimum recording condition, 58 dB CNR was obtained. The film is applicable for the optical disk storage medium working at 830 nm wavelength.

Key words: optical storage material, cyanine dye, synthesis, laser optical disk
