Electroluminescent device |
摘要 |
An electroluminescent device, which emits light by recombination of the carriers injected or excited by light of energy of electrical field, comprising an active layer which includes a semiconductor layer of a super-lattice structure. The layer in the super-lattice structure is changed in effective band gap by an electrical field externally applied to vary the emitted light wavelength. The semiconductor layer of said super-lattice structure comprising an non-single crystalline semiconductor material.
