TY - JOUR ID - TI - Effects of Solvent Properties on Absorption and Fluorescence Characteristics of Two Organic Dyes Used as Random Gain Media AU - Mohammed A. Hameed PY - 2021 VL - 17 IS - 2 SP - 15 EP - 18 JO - Iraqi Journal of Applied Physics المجلة العراقية للفيزياء التطبيقية SN - 18132065 23091673 AB - In this work, the effects of solvent properties on the characteristics of absorption and fluorescence for two laser dyes was studied. Dyes used in this work include Coumarin 5400 and DCM, while the solvents include ethanol, methanol, acetone, propanol and chloroform. Coumarin 5400 dye shows sharp fluorescence peaks in the green band of visible region while the DCM dye shows relatively wide band within 590-630 nm. Therefore, the selection of any dye for random gain medium applications should be performed after determining the most appropriate solvent as the optimum fluorescence characteristics are obtained.
