Abstract:
A semiconductor light emitting element comprising:an active layer made of a nitride compound semiconductor which contains In (indium), Ga (gallium), N (nitrogen), Al (aluminum) and B (boron); a composition ratio of said In being equal to or greater than 45% and having an energy gap smaller than 3.42 eV, said active layer emitting light by band-to-band recombination; a first cladding layer made of a first conduction type nitride compound semiconductor having an energy gap larger than that of said active layer; and a second cladding layer made of a second conduction type nitride compound semiconductor having an energy gap larger than that of said active layer, said active layer being stacked on said first cladding layer, and said second cladding layer being stacked on said active layer; wherein said light emitted by said active layer has a wavelength longer than 364 nm.
