Abstract
The invention relates to the field of light sources, and particularly relates to the field of the electroluminescence. A luminotron of an electron beam pumping comprises an electroluminescent semiconductor mechanism and an excitation source, the electroluminescent semiconductor mechanism is generated on a reflecting metal layer, an electronic gun system is adopted by the excitation source, and the electroluminescent semiconductor mechanism is arranged in the target direction of the electronic gun system. The electroluminescent semiconductor mechanism comprises at least two layers of stacked electroluminescent semiconductor layers, and a semiconductor luminescent structure is composed of the two layers of stacked electroluminescent semiconductor layers. Two adjacent electroluminescent semiconductor layers are electroluminescent semiconductor layers with different forbidden band depths, so a structure of a potential energy trap or multiple potential energy traps is formed in an energy band structure of new formed materials, and therefore conversion efficiency is improved conveniently, and light wavelength is convenient to adjust. The potential energy trap structures are favorable for limiting the semiconductor conducting bands and current carriers on valence bands to a specific energy state, so that the purpose of improving the conversion efficiency is achieved.
Description
technical field [0001] The invention relates to the field of light sources, in particular to the field of electroluminescence. Background technique [0002] At present, there are mainly two types of practical light-emitting mechanisms: one is a traditional gas light source with gas electroglow as the light-emitting mechanism; the other is a solid light source based on a solid light-emitting diode (LED). Both light sources have very obvious drawbacks. The traditional gas light source has poor conversion efficiency, and there are a lot of messy parts in the spectrum, which is not a good monochromatic light, and there is a considerable waste of energy. In addition, traditional gas light sources also have the problem of polluting the environment. Compared with the traditional gas light source, the solid-state light source based on solid-state light-emitting diode (LED) has been improved in some aspects, but it still has the defects of low conversion efficiency and low light in...
