This takes place closer for the electron-transport layer A part of the emissive layer, since in organic semiconductors holes are typically much more mobile than electrons.[citation needed] The decay of this psyched point out brings about a rest of the Strength levels of the electron, accompanied by emission of radiation whose frequency is within the obvious location. The frequency of the radiation depends upon the band hole of the fabric, In cases like this the real difference in Strength between the HOMO and LUMO.
