Transferência de energia entre corantes catiônicos em sistemas homogêneos
Oliveira, Hueder Paulo Moisés de; Machulek Junior, Amilcar; Legendre, Alexandre de Oliveira; Gehlen, Marcelo HenriqueIn this work, the energy transfer by dipole-dipole interaction between cationic dyes in n-alcohols (methanol, ethanol, 1-propanol and 1-butanol) is studied by time resolved and steady state fluorescence measurements. The critical radii of energy transfer were determined by three independent methods; the spectral overlap, fluorescence decay profiles, and relative intensity measurements. In all solvents, R0 value...
