When the electron is combined with the hole, it radiates visible light, so it can be used to make light-emitting diodes.As the indicator light in the circuit and instrument, or as a composition or digital display.Gallium arsenide diodes, phosphating gallium diodes, silicon carbide diodes, and gallium nitride diodes emit blue light.Organic light-emitting diodes and inorganic LED leds are also used for chemical properties.
