Estimated Theoretical Models for Optical Constants for CuO2 doped Polystyrene films

Abstract

An analysis study for optical constants of PS-CuO₂ thin films has been studied. The effect of doping percentage of CuO₂ to polystyrene films onthe optical properties concluded from absorption and transmission measurements by using UV-VIS absorption spectrophotometer in the wavelength range (200-900nm).The refractive index (n), and extinction coefficient (k) have been evaluated experimentally and theoretically. Theoretical equation for refractive index (n) is:-

y =

And estimated theoretical equation for extinction coefficient (k) is:-

This was achieved by making fitting curves for all practical data using [Table curve 2D, version 5.01] program.This helps us to estimate a good similar data between experimental and theoretical results, and estimate any data that is not taken experimentally.
