Abstract
A light-emitting element includes a transparent substrate, a III-V nitride semiconductor layer including rare earth metal elements which is formed on said transparent substrate, and an irradiation source of electron beam which is disposed within 5 mm from the surface of said III-V nitride semiconductor layer so as to be opposite to said III-V nitride semiconductor layer. Then, the rare earth metal elements in the III-V nitride semiconductor layer are excited by electron beams from the irradiation source and a given fluorescence inherent to the rare earth metal elements are emitted.
Claims7
A light-emitting element, comprising:
- a transparent substrate,
- a III-V nitride semiconductor layer including rare earth metal elements which is formed on said transparent substrate, and
- an irradiation source of electron beam which is disposed within 5 mm from the surface of said III-V nitride semiconductor layer so as to be opposite to said III-V nitride semiconductor layer with a vacuum in between the source and the layer,
- whereby said rare earth metal elements in said III-V nitride semiconductor layer are excited by electron beams from said irradiation source and a given fluorescence inherent to said rare earth metal elements are emitted.
