Provided are core/shell type semiconductor nanoparticles including: a core including In and P; and a shell having one or more layers. The semiconductor nanoparticles further include at least Zn, Se, and at least one halogen. In the semiconductor nanoparticles, molar ratios of P, Zn, Se, and halogen each relative to In in terms of atoms are P: 0.20˜0.95, Zn: 11.00˜50.00, Se: 7.00˜25.00, and halogen: 0.80˜15.00. According to the present invention, core/shell type semiconductor nanoparticles that include the core including In and P and the shell including Zn and Se as main components, and have high quantum yield, a small full width at half maximum, and small Stokes shift can be provided. |
