Description

Silicic Acid, Yttrium(3+) Salt, Cerium-Doped is an advanced inorganic luminescent material engineered for high-performance optical applications. This compound matters for its ability to provide stable, efficient luminescence, often serving as a critical host matrix for rare-earth activators. Industries requiring precision phosphors, such as display technology, solid-state lighting, and radiation detection, need this specialized material to achieve specific emission characteristics and long-term stability.

Application

• Phosphor for LED and Display Technology: Used as a host material in phosphor-converted LEDs (pc-LEDs) for backlighting units (BLUs) in LCDs and for general solid-state lighting, where cerium doping provides specific emission bands.
• Scintillation Materials: Employed in radiation detection and medical imaging equipment (e.g., PET scanners) due to its potential for fast decay and high light yield when properly doped.
• Optical Coatings and Sensors: Integrated into thin-film layers for advanced optical filters, laser gain media, or as a sensing matrix in optochemical sensors.
• Advanced Ceramics and Composites: Serves as a precursor or additive in the synthesis of specialty ceramics requiring controlled luminescent or structural properties.
• Research and Development: A key material for academic and industrial R&D in photonics, materials science, and novel luminescent device development.

Quality Control

Our Silicic Acid, Yttrium(3+) Salt, Cerium-Doped is produced under a stringent quality management system. Each batch undergoes rigorous testing for critical parameters including phase purity, particle size distribution, photoluminescence intensity, and dopant concentration. A Certificate of Analysis (COA) detailing these specifications is provided with every shipment to ensure compliance with your technical requirements and to guarantee batch-to-batch consistency for your production processes.

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). This material is hygroscopic (moisture-sensitive) and should be kept in a desiccated environment to prevent degradation of its optical properties. Keep away from strong acids and strong oxidizing agents.
