ABSTRACT:
An electroluminescence element comprises the luminescent layer having a luminescence spectrum in which, in addition to the original emission peaks of the rare earth element, one or more emission peaks exist within a 10 nm wavelength range around each of some original emission peak. The luminescent layer is of a compound semiconductor doped with a rare earth element, deposited by organic metal chemical vapor deposition in which source gases for the rare earth element and elements constituting the compound semiconductor, not containing any halogen element, are supplied to the vicinity of the insulating substrate, separately from halogen or hydrogen halide gas which is also supplied to the vicinity of the insulating substrate.
