Abstract
Semiconductor nanoparticles including Ag, In, Ga, and S are provided. In the semiconductor nanoparticles, a ratio of a number of Ga atoms to a total number of In and Ga atoms is 0.95 or less. The semiconductor nanoparticles emit light having an emission peak with a wavelength in a range of from 500 nm to less than 590 nm, and a half bandwidth of 70 nm or less, and have an average particle diameter of 10 nm or less.
