Abstract
In this work, four kinds of solvents (Acetone, ethanol, methanol, and Water) were used for studying their effect of the spectral properties of the Eosin-y dye. One concentration used for all solvents which was (1*10-5 m/l). The results show that the Fluorescence and Quantum Efficiency decreased with increasing the solvents polarity where the highest value was found in Acetone. Florescence Life-Time, Radiation Life-Time, and stokes shift measured for all solvents. The absorption spectrum shows shifting toward (long) red wavelengths with increasing the viscosity of the solvents. Florescence spectrum showed that the highest value found Acetone and the lowest value found for water where the intensity decreases as the polarity of the solvent increases. All samples can be used as a laser medium for lasers used in the medical field, and the best sample is dissolved in acetone.
