| Aug 20 at 10:39 | comment | added | Rajesh R | It purely depends upon the material used in making the diode. Below, the answers are available correctly. I just add (in simplified manner) that, if the normal diode is made of silicon, its transition of electrons between two energy bands (which is indirect) does not produce visible light. Whereas, in LED the material used like Gallium, indium has direct band gap. If electric field is applied here, the transition between the states, produce light called the process 'Electroluminescence'. | |
