Abstract:
A light-emitting element includes an anode electrode, a QD layer containing QDs, and a cathode electrode, in which the QDs are Cd-free quantum dots having a core-shell structure including a core containing at least Ag, Ga, and at least one of S and Se, and a shell containing at least Zn, and exhibit fluorescence characteristics with a fluorescence full-width at half-maximum of 40 nm or less and a fluorescence quantum yield percentage of 70% or more.
