Abstract

A semiconductor nanoparticle, a method of preparing the semiconductor nanoparticle, and a display device including the semiconductor nanoparticle. The semiconductor nanoparticle includes silver, indium, gallium, and sulfur, and as a radial concentration distribution of silver, indium, and gallium is measured, the semiconductor nanoparticle exhibits a maximum value of a mole ratio of gallium to a total of indium and gallium in a first zone, and in the first zone, a mole ratio of silver to the total of indium and gallium is greater than or equal to about 0.18:1 and less than 1.5:1, and the semiconductor nanoparticle exhibits a quantum yield of greater than or equal to about 85%.
