Abstract
The present disclosure relates to an electroluminescent material ink, comprising a quantum dot material, an organic light emitting material, and an organic solvent. The organic solvent includes a first solvent shown in general formula (I): wherein R0 is CmH2m+1; R1, R2, R3, and R4 are each independently CnH2n+1, 0≤m≤8 and 0<n≤8, or 0<m≤8 and 0≤n≤8. The electroluminescent material ink has good physical parameters and can effectively prevent nozzle blockage.
