Organic luminescent material, includes: host material, TADF sensitizer, and fluorescent-luminescent material; wherein absolute value of difference between LUMO level of the host material and LUMO level of the TADF sensitizer is not more than 0.4 eV, and absolute-value of difference between HOMO level of the host material and HOMO level of the TADF sensitizer is not more than 0.4 eV; absolute-value of LUMO level of the fluorescent-luminescent material is not more than absolute-value of the LUMO level of the host material and the LUMO level of the TADF sensitizer, and/or absolute-value of HOMO level of the fluorescent-luminescent material is not less than an absolute-value of the HOMO level of the host material and absolute-value of the HOMO level of the TADF sensitizer; and emission-spectrum of the host material overlaps an absorption-spectrum of the TADF sensitizer, and emission-spectrum of the TADF sensitizer overlaps absorption-spectrum of the fluorescent-luminescent material.
