Spectroscopic study of absorption and fluorescence rhodamine 610 dye for solution with polymer

Abstract EN

In this study was chosen Rhodamine 610, It was dissolved in ethanol and prepared in concentrations (10 5 ) mole/liter, the absorption and emission spectra of different samples dyes as a laser medium effectively has been prepared and studied at room temperature .

The achieved Results pointed that the absorption peaks were moving toward short wavelengths (BLUE SHIFT) when increasing the ratio of polymer additives and the fluorescence spectrum peaks were moving in the direction of longer wavelengths (RED SHIFT) when increasing the ratio (%50 and %70) of polymer.
