This occurs nearer into the electron-transport layer Portion of the emissive layer, because in natural and organic semiconductors holes are normally much more cellular than electrons.[citation desired] The decay of the thrilled condition ends in a relaxation with the energy levels of the electron, accompanied by emission of radiation whose frequency is during the noticeable location. The frequency of the radiation will depend on the band gap of the material, In such cases the difference in Electricity in between the HOMO and LUMO.
