Spectroscopic ellipsometry study and variability of optical parameters for blend polymer(PVA:POT)thin films

Abstract

The third-order nonlinear susceptibility of blend poly (O-Toluidine-Vinyl Alcohol) were studied as a function of photon energy. The measurement of refractive index (n) and extinction coefficient (k) showed variation in their amount with incident light. In addition, the some optical parameters of the prepared blended polymers were calculated. The optical and electrical conductivity have been measured as a function of photon energy as well as.
