Abstract of the Disclosure

Efficient visible light emission at room temperatures and at wavelengths throughout all portions of the visible spectrum is achieved by minority carrier injection across a p-n junction in semiconductor diodes formed of hybrid solid solutions of IIIa-Va and IIb-VIa compounds. Spontaneous emission and stimulated emission operation of such diodes are described.
