1. A luminescent material, comprising a first compound represented by Formula 1 and a second compound represented by Formula 2:
[A][Cu][X]3  Formula 1
R21R22R23N  Formula 2
wherein, in Formulae 1 and 2,
A is R11R12R13C, R11R12R13R14N, R11R12N═C(R13)—NR14R15, Li, Na, K, Cs, Rb+, Fr, or a combination thereof,
X is F, Cl, Br, I, or a combination thereof,
R11 to R15 are each independently hydrogen, deuterium, —N(Q11)(Q12), a C1-C3 alkyl group, a C2-C3 alkenyl group, a C2-C3 alkynyl group, or a C1-C3 alkoxy group,
Q11 and Q12 are each independently hydrogen, deuterium, a C1-C3 alkyl group, a C2-C3 alkenyl group, a C2-C3 alkynyl group, or a C1-C3 alkoxy group, and
R21 to R23 are each independently hydrogen, deuterium, a substituted or unsubstituted C1-C10 alkyl group, a substituted or unsubstituted C6-C20 aryl group, or a substituted or unsubstituted C7-C20 arylalkyl group, wherein at least one of R21 to R23 is a substituted or unsubstituted C1-C10 alkyl group, a substituted or unsubstituted C6-C20 aryl group, or a substituted or unsubstituted C7-C20 arylalkyl group, and two substituents from R21 to R23 are optionally linked to each other to form a ring.
