Description

Strontium Aluminate, Europium And Dysprosium Doped is a high-performance, inorganic luminescent material known for its exceptional afterglow properties. This compound is valued for its bright, long-lasting phosphorescence, high quantum yield, and excellent chemical stability, making it a superior choice over traditional sulfide-based phosphors. It is primarily sought after by manufacturers in the paints and coatings, plastics, ceramics, security printing, and emergency signage industries for creating glow-in-the-dark products.

Application

• Safety and Emergency Signage: Used in photoluminescent exit signs, pathway markers, and emergency evacuation systems.
• Paints and Coatings: Incorporated into glow-in-the-dark paints for watch dials, instrument panels, decorative art, and architectural features.
• Plastics and Polymers: Masterbatched into engineering plastics, films, and fibers for consumer goods, toys, and automotive trim.
• Ceramics and Glazes: Added to ceramic glazes and glass to produce luminous tiles, tableware, and art pieces.
• Security Printing: Employed as a covert security feature in banknotes, documents, and high-value product packaging.
• Textile Applications: Used in the production of luminous threads and fabrics for safety workwear and fashion.
• Solar Energy Utilization: Investigated for use in spectral conversion layers to enhance the efficiency of solar cells.

Quality Control

Our Strontium Aluminate, Europium And Dysprosium Doped is produced under strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is tested for critical parameters including luminescent intensity, afterglow duration, particle size distribution, and chemical purity. Certificates of Analysis (COA) detailing these specifications are available upon request to support your quality assurance and regulatory compliance needs.

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 nature, the container must be kept sealed to prevent moisture absorption, which can degrade luminescent performance.
