Types of electroluminescence
Electroluminescence is also known as field luminescence. Electroluminescence is a kind of luminescence phenomenon in which electric energy is directly converted into light energy. It includes injection electroluminescence and intrinsic electroluminescence. (1) Injection electroluminescence: electrons and holes are injected directly by the electrode mounted on the crystal. When the electrons and holes are recombined in the crystal, excess energy is released in the form of light. The basic structure of injection electroluminescence is junction diode (LED). (2) Intrinsic electroluminescence: it can [...]
