SEMICONDUCTOR LIGHT EMITTING ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a novel semiconductor light emitting element suitable for use as a white LED. SOLUTION: An underlying layer 2 constituting a semiconductor light emitting element 10 comprises a high crystallinity AlN layer having a half peak width of 90 sec or less in X-ray locking curve. The underlying layer 2 is added with a specified rare earth element. The rare earth element is stimulated by the light emitted from an emission layer 5 to emit light in wavelength characteristic to the rare earth element.
