Abstract
A semiconductor nanoparticle, and a method for producing the semiconductor nanoparticle, and a composite, a color conversion panel, and a display panel including the semiconductor nanoparticle. The semiconductor nanoparticle includes silver, a Group 13 metal including indium and gallium, and a chalcogen element including sulfur and optionally selenium, the semiconductor nanoparticle is configured to emit a green light with an emission peak wavelength of 500 nanometers to 580 nanometers, and a full width at half maximum of about 5 nm to about 70 nm. The semiconductor nanoparticle exhibits a quantum yield of greater than or equal to about 50%, and includes a mole ratio (In+Ga):Ag of about 1:1 to about 3.5:1.
