Quality Control

Our Yttrium Oxide Sulfate, Terbium-Doped is produced under stringent conditions to ensure batch-to-batch consistency and high performance. Each lot undergoes rigorous quality testing, including phase purity analysis and luminescence efficiency measurement, to ensure compliance with industry-specific performance standards. Certificates of Analysis (COA) detailing spectral output, particle size distribution, and chemical composition are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed in a low-humidity environment to prevent degradation of luminescent properties.
