Title: SEMICONDUCTOR NANOPARTICLE, METHOD FOR PRODUCING SAME, AND LIGHT-EMITTING DEVICE
Abstract:
Provided is a semiconductor nanoparticle that demonstrates band-edge luminescence and that has a short light emission peak wavelength. The semiconductor nanoparticle comprises Ag, In, Ga and S, and the ratio of the number of Ga atoms to the total number of In atoms and Ga atoms is 0.95 or less. Moreover, the semiconductor nanoparticle has a light emission peak wavelength within a range between at least 500 nm and less than 590 nm, and emits light having a light emission peak half-width of 70 nm or less. The average particle size is 10 nm or less.
