Abstract

The optical properties of the pure poly(methylmethcrylate) (PMMA) polymer film and PMMA polymer films doped with Solochrome Dark Blue dye at different concentrations were investigated. The films were prepared using the casting technique. The optical absorption and transmission spectra of these films were recorded in the wavelength range 300 - 900 nm for different concentrations using UV-Vis double - beam spectrophotometer. The optical parameters of the Solochrome Dark Blue dye - doped polymer films, reflectance (R), absorption coefficient (α), extinction coefficient (κ), refractive index (n), optical and electrical conductivities (σopt and σelect), and optical energy band gap (Eg), were calculated. The effect of the dye concentration on these parameters was studied. The obtained results show that the Solochrome Dark Blue dye is a promising material for applications in photonic and optoelectronic devices.

Introduction

Nonlinear optical materials have received much interest because of their potential applications in optical devices such as, light emitting diodes, solar cells, optical sensors, optical signal processing, optical switching, optical power limiting, and optoelectronic devices [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15]. The optical and electrical properties of wide range of materials, including organic and inorganic materials, semiconductors, and polymer materials, have been studied to develop practical optical devices [16,17,18,19,20,21,22,23]. Among these materials, organic dyes are of great interest owing to their potential application related to the nonlinear optical (NLO) properties. The polymeric materials can be modified when they doped with suitable organic dyes and their optical nonlinearities are considerably affected This could lead to significant improvement in the optical and electrical properties of these materials. The effect of dye concentration on the values of these parameters was studied
