Electroluminescence is a condition where a material produces light when anelectric field or electric current is passed through it. When the electrons go through the material,they fill the existing electron holes i.e. where there are atoms that are positively charged, lackingelectrons (which are negatively charged). As the electrons fill the electron holes, they emit lighti.e. photons. They are used as diodes because when a semiconductor is doped, two types ofsemiconductors are made in the same crystal and a boundary is formed between the types whichallows current to pass through it in one way (Held, 2009).LEDs are one the most expe
