Optical Properties of Polymer polyvinyl chloride (PVC) doped with DCM Laser-Dye and Tio2 Thin Film

Abstract

Abstract:polyvinyl chlorideis blended with DCM laser dye co-doped with TiO2 nanoparticle. The thin filmswere prepared by using casting method.The optical properties such as absorbance, absorptioncoefficient, refraction index and the optical conductivity of the prepared thin film have been studiedat (30oC).It has been shown from the results that allowed direct electronic transitions energy gapis(1.7eV),while allowed indirect electronic transition energy gap is(1.6 eV).
