Gallium phosphide is a III-V compound semiconductor material with an indirect bandgap, represented by the chemical formula GaP. The product typically appears as yellow or orange-yellow crystalline particles with a bandgap width of approximately 2.26 eV. Renowned for its luminescence in the visible spectrum, high electron mobility, and exceptional chemical stability, it serves as a classic foundational material for manufacturing traditional visible light emitters, high-speed electronic devices, and specialty optical materials.
We offer high-quality gallium phosphide granules in multiple purity grades, particle size specifications, and doping types. Contact us for samples.

Q1: What are the main differences between GaP and GaAs?
A1: They differ in bandgap type and light-emitting color. GaP has an indirect bandgap and is primarily used for visible light emission; GaAs has a direct bandgap and is mainly used for infrared optoelectronic devices and high-speed circuits.
Q2: Why are GaP granules yellow or orange-yellow?
A2: This is determined by its bandgap width of approximately 2.26 eV. The wavelength of photons corresponding to this energy falls precisely within the yellow-green region of visible light.
Q3: What are the primary applications of GaP?
A3: Traditionally, it is primarily used to manufacture visible light LEDs in colors such as red, green, and yellow. It is now also employed in certain high-speed electronic devices and specialty materials.
Q4: What precautions should be taken during use?
A4: Store in sealed, dry conditions and avoid inhaling dust. Follow chemical safety protocols during handling.
