Abstract


In this work, study of absorption and fluorescence spectra for compound (anthracene genitive 2 - methyl naphthalene) dissolved in a polar solvent. The calculated value of the quantity and efficiency found that it increases with ratio doping , and after less than quantity when you reduce the efficiency ratio doping anthracene molecule by molecule 2-methyl naphthalene. Used a diluted concentration to the purpose of minimizing the phenomenon of self-absorption, Calculated the value of the quantity in relation to efficiency anthracene compound dissolved Daye methyl Slfoxayd, the amount of efficiency (qfm=0.32). As a composite record wavelength irritant λex = 365 nm at room temperature. It turns out from this study the presence of my energies activation molecule anthracene doping different proportions of molecule 2 - methyl naphthalene and each activation energy mechanical connecting different which could be interpreted by relying on the theory of packets semiconductor and which proposes a transition charge carriers from the Fermi donor to the packet delivery in the semiconductor negative (n-type) At high temperatures by thermal Excitation.
