sorry i cant explain
gargipnb:
A Zener diode is a particular type of diode that, unlike a normal one, allows current to flow not only from its anode to its cathode, but also in the reverse direction, when the Zener voltage is reached. Zener diodes have a highly doped p-n junction.
A light-emitting diode is a semiconductor light source that emits light when current flows through it. When a current flows through the diode, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence

Zener diodes have a highly doped p-n junction. Normal diodes will also break down with a reverse voltage but thevoltage and sharpness of the knee are not as well defined as for a Zener diode. ... Zener reverse breakdown is due to electron quantum tunnelling caused by a high-strength electric field.
