Influence of the polymer mold on the laser absorption and fluorescence spectra of Rhodamines Dyes

Abstract

This research includes influence of polymer mold of the absorption spectra and fluorescence of Rhodamine B and Rhodamine 6G in the different melts for example chloroform, methanol and dimethyl sulphoxides in the different concentrations (10-4 -10-6 ) mole/liter. The results show that intensity and wave length at top of absorption spectra and fluorescence for dye solutions of two dyes; Rhodamine B and Rhodamine 6G ,should be depend on the increasing polymer size ratio adding ,measure the spectra characters and Photophysical Properties for dyes solutions in the polymer molds (PMMA) ,so results show of this research that absorption spectra and fluorescence for this solutions (dyes solutions) shift towards short waves lengths (high energies) more than liquids solutions for dyes ,also the intensity of absorption spectra and fluorescence increasing, and mixing Dye solution concentration with polymer which appear active effect for polymer which increasing of efficiency of the absorption spectra and fluorescence of Rhodamine B and Rhodamine 6G.
