Abstract

A novel light-emitting device includes a sapphire substrate with a light-emitting layer comprising In.sub.X Ga.sub.1-X N, where the critical value of the indium mole fraction X is determined by a newly derived relationship between the indium mole fraction X and the wavelength .lambda. of emitted light.
