Principle and device structure of electroluminescence

Electroluminescence can be divided into high field electroluminescence and low field electroluminescence. High field electroluminescence is an in vivo luminescence effect. A luminescent material is a semiconductor compound doped with appropriate impurities to introduce a luminescent center or to form a dielectric state. When it comes into contact with an electrode or other medium and its barrier is in the opposite direction, electrons from the electrode or interface state enter the high field of the luminescent material, are accelerated...
