Abstract

A photoexcitation energy transfer process in blends of PbS QDs of different size is considered. An analysis of photoluminescence kinetics shows drastic increase of acceptor decay times. In a triple blend a merger of photoluminescence decay curves recorded at different spectral regions is found. Different pathways of the energy transfer, including the transfer from the in-gap state, are considered.
