Abstract
Provided is an organic light emitting device, including a p-type host layer, an n-type host layer, and an interlayer disposed between the p-type host layer and the n-type host layer, wherein at least one of the p-type host layer and the n-type host layer includes a fluorescent dopant, and a preset distance is present between the fluorescent dopant and the interlayer; the p-type host layer and the n-type host layer are configured to form, together with the interlayer, a spatially separated exciplex under an action of driving voltage; and the fluorescent dopant is configured to absorb energy of singlet excitons generated by the exciplex to emit light.
