ABSTRACT:
An electroluminescence element including at least an insulating substrate, a first electrode, a first insulating layer, a luminescent layer having at least one side constructed and arranged to allow light to pass out of the electroluminescence element, a second insulating layer and a second electrode in this order in a stack, with the components on the at least one side of the luminescent layer being optically transparent. The luminescent layer includes a base material formed from a II-VI compound semiconductor, at least one rare earth element, and at least one halogen element substituted for a VI group element at a lattice site of the VI group element of the II-VI compound semiconductor and located in the vicinity of the at least one rare earth element. The luminescent layer has a luminescence spectrum in which, in addition to the original emission peaks of the at least one rare earth element, some of the original emission peaks have at least one split emission peak located within a 10 nm wavelength range thereof.
