| Abstract | ||
| The fluorescence and absorption spectra of Fluoranthene dissolved in cyclohexane and ethanol were studied and analyzed. The effect of the concentration of this molecule and the polarity of the solvents on the spectral shifts and on relative intensity has been investigated. A computational program was written in order to convert the spectra from grapher to data. Some photophysical parameters such as oscillator strength and quantum efficiency have been calculated. Fluorescence quantum efficiency of Fluoranthene was measured relative to Quinine Sulfate (QS) in 1N H2SO4. The obtained values were (0.5) in cyclohexane and (0.45) in ethanol. | ||
