Study of the Optical Properties PMMA/BDK/MR System Using the Spectroscopic Ellipsometry

Abstract

In this research the optical properties of PMMA/BDK/MR system have been studied. This system was prepared from the Azo-dye of methyl red (MR) in different degrees of acidity and doped with poly methyl methacylate (PMMA). Benzyl dimethyl ketal (BDK) was used as photoinitiartor at certain rates of size, and studying its optical characterstics by using the variable angle spectroscopic ellipsometry. The results show that increasing of basic concentrations of the system the ground energy increases compered with the increasing of acidic concentrations system this leads to decreased of the wave lengths than, and this in turn leads to increase of the storage ability than the data. From this we can conclude that the disks which prepared by basic concentrations are better those prepared at acidic than concentrations.
