Answer:

electroluminescence is observed because of radiative recombination of elections

Answer 2

ELECTROLUMINESCENCE

Electroluminescence is observed because of electric current or field being induced.

GETTING TO KNOW MORE ABOUT ELECTROLUMINESCENCE :

* Electroluminescence is a phenomena in which a material produces light as a result of an induced electrical current or field. When a suitable voltage is given to a p-n junction diode, electrons recombine with electron holes in the device to release energy in the form of photons, resulting in electroluminescence.

* Electroluminescence is light that is emitted in response to an electric current. Since the early 1950s, when Bernanose and colleagues first demonstrated electroluminescence in crystalline thin films of acridine orange and quinacrine, electroluminescence has been used in organic molecules (Bernanose, 1955).

* Dow Chemical researchers used doping to produce AC-driven electroluminescent cells in 1960. When a voltage is supplied to a thin electrode, comparable light emission is observed in some circumstances.
