Effect of Polarity of Solvents on Linear Optical Properties for Organic Dye

Abstract

Abstract In this paper, preparation and study the effect of polarity of two solvents (Dimethyl sulfoxide and acetone) on linear optical properties for solutions of organic dye (Aurintricarboxylic acid) with different concentrations were investigated. This dye has characterized using nuclear magnetic renounce (H-NMR) and Fourier translation infrared (FTIR) devices. Absorption and transmission spectra of samples recorded using UV-VIS spectrophotometer. The results referred to that the samples dissolved in dimethyl sulfoxide solvent had very large linear optical properties as compared with samples dissolved in acetone solvent due to high polarity of dimethyl sulfoxide solvent. As a result, this organic dye can be used as active laser medium and photonic devices
