Product Description
YELLOW-GREEN LED Phosphor for Display Panels and Indoor Lighting
The YELLOW-GREEN Phosphor is an advanced luminescent material engineered for high-performance LED applications. This specialized phosphor delivers exceptional brightness and stability, making it ideal for automotive LED systems, display panels, and indoor illumination solutions.
Product Overview
This phosphor features rare earth elements such as europium or terbium doped into a host lattice, enabling bright yellow-green light emission when excited by blue or near-UV LEDs. The carefully controlled micron or sub-micron particle size (4-15 µm) ensures optimal dispersibility and coating uniformity for superior optical performance.
Key Advantages:
- High quantum efficiency exceeding 70% for energy-efficient illumination
- Excellent thermal stability up to 200-300°C
- Long shelf life exceeding 2 years under proper storage
- Rapid decay time from microseconds to milliseconds
- Vibrant yellow emission at 540-560 nm wavelength
