Gallium selenide powder is a high-purity III-VI group layered compound semiconductor material. Its crystal structure features a hexagonal layered arrangement with a direct bandgap of approximately 2.0–2.2 eV. This powder exhibits unique nonlinear optical properties and excellent responsivity across the visible to infrared spectrum. Due to van der Waals forces binding its monolayers, it is also regarded as an ideal precursor for fabricating two-dimensional materials.
We offer high-quality gallium selenide powder in multiple purity and particle size specifications, with professional sealed packaging available. Contact us.

Nonlinear Optics & Terahertz Technology: Core material for manufacturing mid-infrared lasers, terahertz wave generation, and detection devices.
Optoelectronic Devices: Used in fabricating high-performance photodetectors, thin-film transistors, and flexible optoelectronic devices.
Energy & Catalysis: Applied in photocatalytic water splitting for hydrogen production, pollutant degradation, and as a potential electrode material for lithium-ion batteries.
Q1: How to select the appropriate purity?
A1: Depends on the application. High purity (e.g., 99.99%) is recommended for cutting-edge optoelectronic device research; select based on requirements for certain catalytic or additive applications.
Q2: How should the product be stored?
A2: This product is sensitive to air and must be stored sealed in a dry, light-protected, inert gas environment to prevent oxidation.
Q3: What are the main advantages of GaSe powder?
A3: Its core strengths lie in the exceptional nonlinear optical properties derived from its layered structure and its application potential as a two-dimensional material.
Q4: Are there safety risks during use?
A4: Selenides exhibit moderate toxicity. Avoid inhaling dust during handling and operate in well-ventilated areas while wearing protective equipment.
