STUDY OF ELECTRICAL ENERGY LEVELS OF THE LASER ACTIVE MEDIUM
Journal Title: Academic Research International - Year 2016, Vol 7, Issue 5
Abstract
In this paper has been studied the electrical energy levels of molecules experimentally. The study was conducted using different concentrations solvents to see the effect of concentrations - (0.5 x 10-3, 1x10-3, 0.5x10-4, 1x10-4,1x 10-5) Ml to pop pop dye with chloroform- on the absorption and fluorescence spectra and linear optical properties (absorption coefficient, refractive index, life time and quantum yield of florescence level). Ranged wavelengths of the absorption spectra for pop pop solutions between (352-337)nm in chloroform. All these wavelengths within the transitions in molecular electrical orbits at type (n®p*). The results were shifted absorption and emission (fluorescence) spectra peaks toward shorter wavelengths (blue shift), and increase the value of linear absorption coefficients and linear refractive index when increasing the concentration of the solution. It shows through the results that the life time of fluorescence increases and quantum yield decreases with increasing concentration of the solution.
