Technology of Bright IR LED

Bright IR LED technology involves the use of semiconductor materials to emit infrared light. The most commonly used materials for IR LED are gallium arsenide (GaAs), gallium phosphide (GaP), and indium gallium nitride (InGaN). These materials can emit infrared light at different wavelengths, depending on their composition and structure.

The manufacturing process of bright IR LED involves several steps. First, a p-n junction is formed between the semiconductor materials. Then, a metal contact is added to the n-type layer to facilitate the injection of electrons. Finally, a phosphor layer is deposited on the LED to convert the emitted infrared light into visible light, making it more visible to the human eye.
