وصف الابستركت (Abstract)
The achieved Results pointed that the absorption peaks are moving toward short wavelengths (BLUE SHIFT) when increasing the ratio of polymer additives and the fluorescence spectrum peaks are moving in the direction of longer wavelengths (RED SHIFT) when increasing the ratio (%20 and %40) of polymer
الوصف الكامل (Full Abstract)
In this study were chosen coumarin (480), and It was dissolved in ethanol and prepared in concentrations (10 4 ? ) mole/liter, the absorption and emission spectra of different samples dyes as a laser medium effectively been prepared and studied at room temperature . The achieved Results pointed that the absorption peaks are moving toward short wavelengths (BLUE SHIFT) when increasing the ratio of polymer additives and the fluorescence spectrum peaks are moving in the direction of longer wavelengths (RED SHIFT) when increasing the ratio (%20 and %40) of polymer
