Specialty Functional Additives: Additive for high-performance glass, ceramics, or coating materials to impart unique optical or electrical properties.
Q1: How do I select the appropriate purity grade for my application?
A1: This depends on your specific application. For fundamental research or additives, 99.95%-99.99% (3N-4N) purity is suitable; for fabricating high-performance semiconductor devices, 99.999% (5N) or higher purity is recommended.
Q2: How should the product be stored?
A2: This product is moisture-sensitive. It must be stored sealed in a cool, dry environment. After opening, handling and storage under an inert atmosphere are advised.
Q3: Are there safety precautions when using this material?
A3: Standard operating procedures must be followed. This material exhibits moderate toxicity. Avoid inhaling dust or skin contact during handling. Wear protective equipment in a well-ventilated area.
Q4: What advantages does gallium sulfide (Ga2S3) offer in optoelectronic devices?
A4: Its core advantage lies in its tunable wide bandgap, enabling efficient absorption and emission of visible light. This makes it highly suitable for fabricating high-efficiency visible light detectors, LEDs, and novel ultra-thin (two-dimensional) optoelectronic devices.
