Study the Optical Properties of (C52H54N4O12) Dye

Abstract

Abstract This paper includes investigation of linear optical properties for malachite green oxalate (M.G.O) dye melted in ethanol solvent at several concentrates (2×10−5, 1×10−5, 5×10−6)Ml and for (M.G.O) dye films and optical properties of (M.G.O) dye films prepared by casting method for concentrate solution10−3 Ml. Measurement result using (UV-Vis) spectrophotometer to measure (absorbance, transmittance, absorption coefficient (α˳), refractive index( n˳ and energy gap) were found two transitions wavelengths (428,622) nm when dye is dissolved in ethanol and(435,646) nm when preparing films. Linear optical properties were studied for the three concentrations and it was found increased absorption coefficients and refractive index by rising concentration.
