Concentration and pump intensity dependent gain studies for disodium flourescein (FDS), cresyl violet (CV), and rhodamine- 590 (Cl) and cresyl violet mixture

Comparative photophysical and energy transfer studies of C480:C535 binary dye mixture in solid and liquid environments

“…In the liquid medium, The drop in gain after a particular acceptor concentration range maybe predominantly attributed to the inner filter effect at higher concentrations [24] or due to photoquenching or concentration quenching. The gain studies of C535 in C480:C535 binary dye mixture were repeated in MMA and EtOH using donoracceptor concentrations optimized as above.…”

“…The energy transfer studies in a binary dye mixture of Coumarin 450 as donor and Coumarin 535 as acceptor, in MPMMA and MMA+ EtOH, have been studied successively by our group [24]. The energy transfer technique between Coronene and Rhodamine 6G in PMMA matrices, the influence of energy migration in energy transfer in a dye pair of AcriflavineRhodamine B in PMMA using excited state dynamics of the donor and acceptor molecules, and the excitation energy transfer from Acriflavine to Rhodamine 6G in PMMA at room temperature have all been studied extensively by various authors [25][26][27].…”
