Abstract
The measurement of triplet decay time (Τp) and the relative yields of phosphorescence to fluorescence (φp/φf) have been made in solutions of xanthene dyes. The value of φp/φf increases while that of Τp decreases as the concentration of the solution is increased. The rate constants kp, kqp and kis have been estimated. It is found that the values of kqp and kis increase while that of kp remains substantially constant for the entire range of concentration. The deuterium solvent effect is observed in Τp and φp.
