Abstract
Semiconductor nanoparticles are provided. The semiconductor nanoparticles contains Ag, at least one of In and Ga, and Se. An Ag content is 10 mol % to 30 mol %, a total content of the at least one of In and Ga is 15 mol % to 35 mol %, and an Se content is 35 mol % to 55 mol % in the semiconductor nanoparticles. The semiconductor nanoparticles emit light having an emission spectrum with a peak emission wavelength in a range of 500 nm to 900 nm, and a half bandwidth of 250 meV or less upon irradiation with light in a wavelength range of 350 nm to less than 500 nm.
