The wavelength emitted by the diode can be within the visible, infrared, or ultraviolet spectrum. Multicolored LEDs can emit a range or number of different wavelengths. It is important that the color ...

The diode is built by joining together two semiconductor materials: an N-type material (rich in negative carriers or free electrons) and a P-type material (rich in positive carriers or holes). The ...

The evolution of LED technology has led to the development of several types, primarily inorganic LEDs, OLEDs, and QLEDs. Inorganic LEDs are known for their durability and energy efficiency, making ...

The semiconductor light-emitting diode, or LED, is a key component of today's technology. Modern households have numerous tiny glowing indicators — provided by LEDs — that are used for reading ...
