Silicon Nitride Ceramics:

Silicon nitride light-emitting diodes, abbreviated as LEDs, are commonly used light-emitting devices that emit energy through the recombination of electrons and holes, and are widely used in the field of lighting. Light-emitting diodes can efficiently convert electrical energy into light energy, and have a wide range of uses in modern society, such as lighting, flat panel displays, medical devices, etc. This electronic component appeared as early as 1962. In the early days, it could only emit red light with low luminosity. Later, other monochromatic versions were developed. The light that can be emitted has spread to visible light, infrared light and ultraviolet light, and the luminosity has also increased to a considerable luminosity. And the use has also been used as indicator lights, display panels, etc. at the beginning; with the continuous advancement of technology, light-emitting diodes have been widely used in displays and lighting. Light-emitting diodes are referred to as LEDs for short. Made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc. When electrons and holes recombine, they can emit visible light, so they can be used to make light-emitting diodes. Used as indicator lights in circuits and instruments, or composed of text or digital displays. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Due to chemical properties, it can be divided into organic light emitting diode OLED and inorganic light emitting diode LED.
