Abstract: An organic solid up-conversion material contains a triplet sensitizer and an organic luminescent material. The triplet sensitizer and the organic luminescent material satisfy relations of a numerical formula (Numerical Formula 1) and a numerical formula (Numerical Formula 2), and the triplet sensitizer and the organic luminescent material form a solid solution crystal. T1(M1)≥T1(M2)  (Numerical Formula 1) S1(M2)>S1(M1)  (Numerical Formula 2) (S1(M1) is the lowest singlet energy of the triplet sensitizer, T1(M1) is the lowest triplet energy of the triplet sensitizer, S1(M2) is the lowest singlet energy of the organic luminescent material, and T1(M2) is the lowest triplet energy of the organic luminescent material.)
