Abstract
In this paper, spin-coated thin films of phthalocyanine dye were prepared. Absorption spectrum of the thin film shows a comparatively broad absorption at the wavelength region 630 - 770 nm and there is a steep absorption edge at the wavelength 750 nm, which is crucial to high reflectivity. Optical parameters of the thin film was measured by a spectroscopic ellipsometer. Extinction coefficient found to be very little at the wavelength 780 - 810 nm. 5-in CD-R discs made of this dye exhibit good performance after recorded in Yamaha 20 speed recorder. Jitters of land or pit are less than 35 ns and the 3T-11T's signals show very good quality. This dye is promising recording media for CD-R for much higher speed recording in the future.
