The fluorescence emmission spectra of two aromatic hydro-carbons (naphthalene and pyrene) wore measured for identification and proper classification. The lifetime measuring instrument was calibrated and tested with 1μg/ml solution of quinine sulphate in. 0.05M sulphuric acid. A value of 21.50 ns was obtained for the fluorescence lifetime of quinine sulphate. The fluorescence lifetimes of naphthalene and pyrene were then determined with this system using four different concentration of each sample. A vacuum system was also constructed for removing the dissolved oxygen in these aromatic hydrocarbons. After degassing the measurement was repeated for each sample. The monomer fluorescence lifetime of 437.50 ns was obtained for naphthalene while 577.02 ns was obtained for pyrene. 2019-10-21T15:57:42Z 2019-10-21T15:57:42Z 1985 Thesis https://ir.oauife.edu.ng/handle/123456789/5005 en application/pdf Obafemi Awolowo University, Ile Ife, Nigeria |
