Through researching the exciton dynamic of InP/ZnSe QDs with different shell thicknesses, we found that a thick shell can stabilize the 1P e energy state of the InP core, thus decreasing the spectral overlap in the overall QDs. Here, we synthesized pyramidal InP/ZnSe QDs based on aminophosphine as the phosphorus precursor by adding hydrofluoric acid to remove the oxides on the InP core surface before the growth of a ZnSe shell. However, their use for luminescent solar concentrators (LSCs) has been limited owing to their low optical efficiency, which is because of the energy loss due to the strong overlap between their emission and absorption spectra. Colloidal indium phosphide (InP) quantum dots (QDs) have attracted a great attention for their excellent optical properties, and they are a promising candidate for potential applications in optoelectronic devices, such as photocatalysis, light emitting diodes, and bioimaging.
