Gallium selenide Powder is a crucial III-VI compound semiconductor material with the chemical formula Ga₂Se₃. The product is a high-purity reddish-black crystalline powder featuring a cubic crystal structure and a moderate direct bandgap (approximately 2.0–2.6 eV), exhibiting excellent responsivity across the visible to infrared spectrum. It exhibits relatively stable chemical properties at room temperature. With its unique photoelectric conversion efficiency, nonlinear optical properties, and emerging biological activity, it has become a key foundational material for optoelectronic devices, infrared technology, and cutting-edge interdisciplinary research.
We offer high-purity gallium selenide powder in multiple purity and particle size options, supporting customized packaging from R&D to production, along with quality assurance testing. Contact us for a quote.

Q1: How to select the appropriate purity grade?
A1: This depends on your end application. For fundamental research and certain functional additives, 99.99% (4N) grade is suitable; for fabricating high-performance semiconductor films or devices, 99.999% (5N) or higher ultra-high purity is recommended.
Q2: How should the product be stored?
A2: Store this product sealed in a cool, dry environment at room temperature. Strictly isolate from moisture to prevent degradation. Handling under an inert atmosphere is advised.
Q3: Is this material safe to use?
A3: Selenides exhibit moderate toxicity. Avoid inhaling dust during handling. Work in well-ventilated areas while wearing protective equipment and strictly follow the guidelines provided in the Material Safety Data Sheet (MSDS).
Q4: What are the core advantages of Ga2Se3 in optoelectronic devices?
A4: Its core advantages lie in its moderate direct bandgap and high photoelectric conversion efficiency. It effectively absorbs visible light and converts it into electrical signals or catalyzes reactions, making it highly suitable for manufacturing efficient thin-film solar cells and detectors.
