Modulation of fluorescence resonance energy transfer efficiency for white light emission from a series of stilbene-perylene based donor–acceptor pair

Abstract

The discovery of white light emitting materials is a highly emerging field. Stilbene moiety containing three donor molecules and perylene moiety containing three acceptor molecules have been selected for various donor–acceptor sets in Förster resonance energy transfer (FRET). An attempt has been made to correlate energy transfer efficiency with the emission of white light. It has been found that generally good energy transfer efficiency leads to significant white light emission, while poor energy transfer efficiency shows no significant emission of white light. Results of computational studies also match well with experimental results for measuring energy transfer in FRET. Results of this study are promising for making new white light emitting materials in the future based on the proper selection of donor–acceptor pair in FRET.
