The results of processing the luminescence attenuation kinetics of an InP/InAsP/InP hybrid semiconductor nanostructure with deposited colloidal layers of CdSe/ZnS quantum dots (QD) under excitation at wavelengths of 532 and 633 nm and temperatures of 80 and 300 K. Such a nanostructure is characterized by a significant increase in the duration and intensity of the luminescence of the INASP nanostructure. The mechanism of increasing the luminescence duration is presumably associated with the interaction of the QD CdSe/ZnS-TORO colloid with the InP surface, which leads to the formation of new hybrid states in the band gap that are energetically close to the radiating state and are able to capture electrons, which in turn is compensated by the increasing role of the electron reverse transfer process, which leads to an increase in the duration of radiative recombination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
