PG - 2093-6 AB - Applying Forster theory, the energy transfer between acridine orange (AO) and rhodamine 6G (R6G) was investigtaed. It was found that in the solution of dodecyl benzene sulfonic acid sodium (DBS), effective energy transfer can occur between AC and rhodamine 6G even when the concentration of the dyes is very low. The mechanism of energy transfer between AO and rhodamine 6G was studied. When the energy transfer occurs, the fluorescence of AO is quenched, the type of quenching is static. Based on the mechanism of Forster energy transference, the thermodynamic parameters, enthalpy change (deltaH) and entropy change (deltaS), were calculated according to Van't Hoff equation, which indicates the acting force between AO and R6G. The transfer efficiency of energy and the distance between AO and R6G were found. It is indicated that the course of action is single static quenching.
