Study of Linear Optical Properties of Acridine-orange Laser Dye

Abstract

In this research, the linear optical properties and the effect of concentration of the solution on absorption spectra and fluorescence spectra of the acridine_orange dye. It was prepared three concentrations acridine_orange dye dissolved in ethanol (1*10^-3, 1*10^-4, 1*10^-5) M. It was measured spectroscopic properties of the dye solution and for all concentrations (absorption coefficient, refractive index, and fluorescence life-time and quantum yield of florescence level). The results showed that the linear absorption coefficient and linear- refractive index increase with solution concentration increasing and (life-time of fluorescence increases, quantum yield decreases) with solution concentration increasing.
