Introduction to IR LED NM

What is IR LED NM?

In the field of optoelectronics, the term "IR LED NM" refers to Infrared Light Emitting Diode with a specific Nanometer (nm) value. IR LEDs, or infrared light-emitting diodes, are semiconductor devices that emit infrared light when an electric current is applied to them. The "NM" in IR LED NM denotes the specific wavelength of the emitted light, measured in nanometers. This wavelength determines the color and the range of applications for the IR LED.

How does an IR LED work?

An IR LED consists of a PN junction, where the P-type and N-type semiconductor materials are combined. When an electric current is applied to the diode, electrons from the N-type material are injected into the P-type material. As these electrons recombine with the holes in the P-type material, they release energy in the form of photons. The energy of these photons corresponds to the bandgap of the semiconductor material used, which determines the wavelength of the emitted light. In the case of IR LEDs, the semiconductor material typically used is a compound semiconductor, such as AlGaAs or InGaAs, which has a bandgap that corresponds to the infrared region of the electromagnetic spectrum. The specific nm value of the IR LED determines the color of the emitted light, with shorter nm values corresponding to higher frequencies and shorter wavelengths.
