Question

what is the chemical used in LED bulbs and ciffel bulbs?

Answer 1

Answer:

The main semiconductor materials used to manufacture LEDs are: Indium gallium nitride (InGaN): blue, green and ultraviolet high-brightness LEDs. Aluminum gallium indium phosphide (AlGaInP): yellow, orange and red high-brightness LEDs. Aluminum gallium arsenide (AlGaAs): red and infrared LEDs.

• LEDs are made of semiconducting materials, materials which conduct electricity under some conditions but not others. Several different semiconducting materials can be used in LEDs, but a lot of them are gallium-based, for example gallium nitride and gallium phosphide.
