Abstract
Fluorescent semiconductor quantum dots (QDs) from indium phosphide (InP) are a promising low-toxicity alternative to cadmium chalcogenide-based quantum dots. It is expected that if comparable optical characteristics are achieved, InP QDs can successfully displace Cd-containing nanocrystals from their traditional applications in optoelectronics and biomedicine. Unfortunately, at present the optical parameters of InP quantum dots are inferior to those of their Cd-containing counterparts, and the methods for their production require additional optimization. This paper presents the results of experiments to optimize the synthesis procedures of InP QDs using tris-diethylamine phosphine as a phosphorus precursor. It is shown that optimization of heating modes of reaction mixtures during the synthesis allows to obtain highly homogeneous InP QDs with improved optical characteristics.
