Introduction to High Power Violet LED

High power violet LED refers to a type of LED with a high luminous intensity and a shorter wavelength than blue LED. The violet LED has a wavelength range of 380-450nm, which is close to the ultraviolet region. Due to its high energy and strong excitation ability, the high power violet LED has been widely used in various fields, such as optical communication, display, and medical treatment.

Development of High Power Violet LED

The development of high power violet LED can be traced back to the 1990s. At that time, the development of blue LED technology had reached a bottleneck, and the research on violet LED became a hot topic. In the early 2000s, with the continuous optimization of material structure and growth technology, the luminous intensity of high power violet LED reached a new level. Since then, the market demand for high power violet LED has been growing rapidly.

Material and Structure of High Power Violet LED

The material structure of high power violet LED is mainly composed of gallium nitride (GaN) and indium gallium nitride (InGaN). The GaN crystal has a direct bandgap, which is conducive to the emission of high-power violet light. The InGaN crystal has a smaller bandgap, which can effectively extend the wavelength of the emitted light. The structure of high power violet LED generally includes the following layers: p-type InGaN, n-type GaN, and p-type GaN.
