Abstract
A core-shell type quantum dot comprising, a semiconductor nanocrystal core including at least In and P, and having group III-V elements as constituent elements and a single or a plurality of semiconductor nanocrystal shells having group II-VI elements as constituent elements covering the semiconductor nanocrystal core, wherein a buffer layer comprising semiconductor nanocrystals having group II-V elements as constituent elements is included between the semiconductor nanocrystal core and the semiconductor nanocrystal shell. As a result, quantum dots using group II-V semiconductor nanocrystals as a core and having improved fluorescence emission efficiency are provided.
