Energy transfer in 9 amino acridine hydrochloride hydrate to acriflavin and 9 amino acridine hydrochloride hydrate–acriflavin–rhodamine B-doped PVA films

Abstract

In the present study, excitation energy transfer between the dye pair 9 amino acridine hydrochloride hydrate (9AAHH)–acriflavin and the ternary 9AAHH–acriflavin–rhodamine B (RB) dye system doped in poly-vinyl alcohol (PVA) films was investigated at room temperature. For 9AAHH–acriflavin dye pair, the energy transfer parameters, viz overlap integral ΩDA and critical transfer distance R OA, equalling 1.4×10−13 l cm3 mol−1 and 45.23 Å, respectively, have been obtained. Energy transfer from 9AAHH to RB via acriflavin has also been investigated. These two and three dyes doped transparent polymer films of PVA can be used as efficient materials in luminescent solar collectors.
