Abstract

In this study was chosen Rhodamine 610, It was dissolved in ethanol and prepared in concentrations ( ) 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.

في هذه الدراسه اختيرت صبغة الردامين 610 واذيبت في محلولالايثانول وحضرت بتركيز 10-5 مول لكل لتر, اطياف الانبعاث والامتصاص للصبغات الليزريه اختلفت على نحو فعال كوسط ليزري تم اعداده بدرجة حرارة الغرفه. النتائج التي تحققت تشير ان قمم الامتصاص زحفت باتجاه الاطوال الموجيه القصيره(اللون الازرق) عندم زيدت نسبة البوليمر المضافهوقمم طيف الفلوره زيحت باتجاه الاطوال الموجيه الطويله (اللون الاحمر) عند زيادة نسبة 50% و70% من البوليمر .
