Abstract

Abstract Image

Transient energy transfer mechanism in single quantum dot−dye hybrids was studied by following the evolution of the emission decay profile in addition to the ratiometric shift between the donor and acceptor. This study was made possible by the combined use of multiparameter spectroscopy and model-free statistical approach.
