Silicate Yellow-Emitting Phosphor for LED Backlighting D50 15.8 ± 1.0µm
Research-grade luminescent powder
Product Overview

Silicate yellow-emitting phosphor is a broad-band luminescent conversion powder for LED backlighting. This specification provides a peak emission wavelength of 565.6 ± 0.2 nm, a dominant wavelength of 550.8 ± 1.0 nm and a full width at half maximum of 86.9 ± 0.5 nm.

The chromaticity coordinates are (0.406, 0.565), and the median particle size (D50) is 15.8 ± 1.0 µm. These defined spectral, colorimetric and particle-size parameters support phosphor comparison, backlight formulation and optical-material selection.

The silicate phosphor system combines high quantum efficiency with resistance to phosphor segregation and stable batch characteristics. It is intended for LED backlighting where luminous efficacy, color blending and manufacturing consistency are important selection considerations.

This silicate yellow-emitting phosphor must be kept sealed, dry, and protected from direct light to maintain its luminescent properties. Airborne dust must be minimized during transfer, and suitable laboratory protective equipment must be used when handling this fine powder.

  • Moisture Sensitivity: The phosphor must be stored in a sealed, moisture-resistant container to prevent degradation from ambient humidity.
  • Light Sensitivity: Exposure to direct light should be avoided to preserve the phosphor's optical performance.
  • Dust Minimization: Airborne dust must be minimized during handling to reduce inhalation risk and cross-contamination.
  • Personal Protective Equipment: Suitable personal protective equipment including gloves, dust mask, and safety goggles is required when handling the phosphor.
  • Safety Documentation: Applicable safety documentation must be reviewed before handling the phosphor material.

This procedure describes the recommended steps for safely handling and storing the silicate yellow-emitting phosphor powder. Following these steps minimizes exposure risk and maintains product integrity.

Required Equipment: Chemical-resistant gloves, Dust mask (N95 equivalent), Laboratory safety goggles, Sealable moisture-resistant container

  1. Inspect container

  2. Don protective equipment
    Don suitable personal protective equipment including gloves, dust mask, and safety goggles.
  3. Transfer phosphor
    Transfer the phosphor powder using techniques that minimize airborne dust, such as slow pouring in a well-ventilated area.
  4. Seal container
    Seal the phosphor container immediately after use to prevent moisture ingress.
  5. Store properly
    Store the sealed container in a dry, dark location away from direct light.

    Dispose of any waste phosphor material according to local regulations for fine chemical powders.

How does the 86.9 nm FWHM of the AF-SILY566-16 silicate phosphor affect color blending in LED backlighting compared to narrower-band phosphors?

The 86.9 ± 0.5 nm full width at half maximum provides a broad spectral output that supports wide color gamut blending in LED backlighting. This broader emission, centered at a peak wavelength of 565.6 ± 0.2 nm, enables smoother color mixing and more uniform chromaticity across the backlight panel compared to narrower-band phosphors, which may produce sharper but less flexible color points. The defined chromaticity coordinates of (0.406, 0.565) further aid in predictable color formulation.

What are the critical handling and storage requirements for this silicate yellow-emitting phosphor to prevent degradation?

The phosphor must be kept sealed, dry, and protected from direct light to maintain its luminescent properties and prevent moisture-induced degradation. During transfer, airborne dust should be minimized, and suitable laboratory protective equipment must be used. These precautions are essential because the silicate material system is sensitive to environmental exposure, which can alter particle size distribution or reduce quantum efficiency.

Can the AF-SILY566-16 phosphor be used in backlight formulations requiring resistance to phosphor segregation during dispensing?

Yes, the silicate phosphor system is specifically designed with resistance to phosphor segregation, making it suitable for consistent backlight formulation during dispensing and curing processes. This characteristic, combined with stable batch-to-batch performance and a median particle size of D50 15.8 ± 1.0 µm, supports uniform dispersion in silicone or epoxy matrices without settling or agglomeration issues.

This silicate yellow-emitting phosphor (AF-SILY566-16) provides a defined peak emission at 565.6 ± 0.2 nm with a broad FWHM of 86.9 ± 0.5 nm and controlled chromaticity (0.406, 0.565), enabling precise color blending for LED backlighting. Its resistance to phosphor segregation and stable batch characteristics support consistent formulation, though the powder requires sealed, dry, light-protected storage and careful handling to minimize airborne dust during lab deployment.

Positive

  • Defined spectral output: Peak emission at 565.6 ± 0.2 nm, dominant wavelength 550.8 ± 1.0 nm, and FWHM 86.9 ± 0.5 nm provide reproducible color conversion for backlight formulations.
  • Process-oriented stability: Resistance to phosphor segregation and stable batch characteristics support consistent manufacturing and color blending in LED backlighting applications.

Trade-offs

  • Strict handling requirements: The phosphor must be kept sealed, dry, and protected from light; airborne dust must be minimized during transfer, requiring suitable laboratory protective equipment.
  • Particle size sensitivity: Median particle size D50 15.8 ± 1.0 µm may influence dispersion behavior and settling in liquid formulations, requiring process optimization for uniform coating.
