摘要： An object of the present invention is to provide a core/shell type quantum dot material capable of increasing the photoluminescence quantum yield and a method of manufacturing the same. The quantum dot material according to one embodiment of the present invention is a quantum dot material comprising a plurality of nanoscopic core-shell structures, each nanoscopic core-shell structure including a nanocrystalline core including phosphorus and indium, a shell disposed on the nanocrystalline core, and a modifier comprising at least one of chlorine and bromine, wherein the content of chlorine and/or bromine is within a range of 2 to 15 mass % of the quantum dot material.
