Product Advantages
Extreme Thermal Stability for High-Power Applications
Engineered to withstand continuous operation at 300°C and peak temperatures up to 500°C, this nitride phosphor maintains stable luminous output in high-heat LED packaging environments where junction temperatures routinely exceed 150°C. The cubic crystal structure of (Sr,Ca)AlSiN₃:Eu²⁺ resists thermal quenching—a common failure mode in stadium lights, industrial high-bays, and transportation lighting where heat accumulation causes rapid brightness degradation in standard phosphors. This thermal reliability extends fixture lifespan and reduces warranty claims for manufacturers serving industrial and commercial lighting sectors.
High Luminous Efficiency for Reduced Operating Costs
With 100 lm/W efficiency (measured at 25°C, 350mA), this phosphor minimizes power consumption in LED fixtures—directly reducing electricity costs for end-users operating high-power or continuous-use lighting. The narrow emission bandwidth (FWHM 74±1nm) centered at 610-670nm ensures minimal energy waste through spectral spillover, while maintaining high brightness output. For manufacturers targeting energy-regulated markets, this efficiency level supports compliance with standards such as the EU ErP Directive and US Department of Energy requirements.
ISO-Certified Quality with Full Test Documentation
Our phosphor is manufactured under ISO quality management systems, ensuring batch-to-batch consistency critical for large-scale LED production. Every bulk order includes comprehensive test reports covering luminous efficiency, spectral distribution, particle size analysis, and thermal stability data—enabling your quality assurance team to verify performance before integration. This documentation supports customer audits, regulatory compliance verification, and end-customer specifications in global markets.
IOS Compliance for Global Market Access
This phosphor is lead-free, mercury-free, and IOS 2.0 compliant, meeting restricted substance regulations in the EU, North America, Japan, and other eco-sensitive markets. We provide third-party IOS test reports with bulk orders, eliminating compliance risks that could delay customs clearance or trigger product recalls. This regulatory readiness is essential for manufacturers serving multinational clients or exporting to multiple regions.
Production-Ready Design for Manufacturing Efficiency
Particle size control (5-20 microns, D50=15.5±2.0μm) ensures uniform dispersion in silicone binders, minimizing "color spotting" defects in LED arrays that can increase production waste. Optimized for 450-460nm blue LED chips—the industry standard representing over 80% of LED production—it integrates seamlessly into existing manufacturing lines without requiring chip or packaging modifications. The narrow FWHM (74±1nm) reduces batch-to-batch color variation, ensuring consistent chromaticity coordinates (x=0.6500±0.003, y=0.3500±0.003) across production runs.

Packaging and Integration Guidelines
To achieve optimal performance in LED production, we recommend the following handling and formulation practices:
Phosphor Blending
For high-CRI white LEDs, combine red phosphor with yellow-green phosphor (535nm) in ratios adjusted for target CCT (e.g., 1:4 for 3000K warm white, 1:5 for 4000K neutral white). For grow lights requiring pure red spectrum, pair with 450-460nm blue chips without additional phosphors.
Silicone Compatibility
This phosphor is tested with standard LED-grade silicones. Use low-viscosity silicones (≤5000 cps) for uniform dispersion, and vacuum degas before curing to eliminate air bubbles that can cause optical defects.
Curing Parameters
Cure at 150-180°C for 1-2 hours. Avoid exceeding 200°C during any processing step to maintain phosphor efficiency and prevent thermal stress to the crystal structure.
Dispersion Techniques
For high-volume production, use planetary mixers with vacuum degassing function. Mix at low speeds (300-500 rpm) for 15-20 minutes to achieve uniform distribution without particle damage.
Storage Conditions
Store in sealed containers at 15-25°C, relative humidity ≤60%. Avoid exposure to acids, bases, strong oxidizers, or direct sunlight. Shelf life is 24 months under proper storage conditions.
Anti-Settling Tips
For high-volume production, use thixotropic silicone additives to prevent phosphor sedimentation during pre-cure phases and maintain uniform color throughout the LED array.
