Pure Green, Yellow Green LED Chips

Description

Pure green LED chips emit light in the green spectral range without any visible color shift or tint. The wavelength range of pure green LED chips is typically between 520 and 540 nanometers (nm). These chips are made using indium gallium nitride (InGaN) or gallium nitride (GaN) materials, which are doped with specific impurities to emit pure green light when an electrical current is applied.

Yellow-green LED chips emit light in a range of wavelengths between green and yellow, typically around 570 nanometers (nm). These chips are made using materials such as aluminum gallium indium phosphide (AlGaInP) or gallium arsenide phosphide (GaAsP), which are doped with specific impurities to produce the desired color.

Pure green and yellow-green LED chips are used in a variety of applications, such as traffic signals, automotive lighting, backlighting for displays, and general lighting. They are also used in horticultural lighting for plant growth and in medical applications for phototherapy.

The performance of pure green and yellow-green LED chips is typically characterized by their efficiency, color quality, and lifetime, which are influenced by factors such as the quality of the semiconductor material, the design of the p-n junction, and the thermal management of the device.
