This phosphor must be stored sealed, dry, and protected from direct light to prevent degradation. Airborne dust should be minimized during transfer, and appropriate laboratory protective equipment must be used.

  • Storage requirements: Seal the container and store in a dry, light-free environment.
  • Dust control: Minimize airborne dust during powder transfer to avoid inhalation and contamination.
  • Personal protection: Use suitable laboratory gloves, safety glasses, and dust mask when handling.
  • Safety documentation: Review the applicable safety data sheet before handling.
  • Excitation source requirement: Use an excitation source within 440–470 nm for optimal performance.

What is the typical quantum efficiency range for the AF-ONBG500 oxynitride phosphor, and how does it vary within a batch?

The quantum efficiency is specified as 60–80%. The exact value within this range depends on the specific emission wavelength and particle-size selection within the product's defined parameter ranges. This variation is inherent to the phosphor's batch-to-batch and grade-to-grade performance, so selection should be based on the required spectral and physical specifications.

Can the AF-ONBG500 phosphor be integrated into a high-power full-spectrum LED package without additional spectral filtering?

Yes, the phosphor is specifically designed for blue-excited high-power full-spectrum lighting. Its emission peak range of 495–505 nm and recommended excitation range of 440–470 nm allow direct integration with standard blue LED chips. However, the final spectral output will depend on the specific CIE chromaticity coordinates (x: 0.247–0.264, y: 0.515–0.535) and the chosen particle size (d50: 8–25 µm), which influence scattering and color mixing.

What handling and storage conditions are required to maintain the AF-ONBG500 phosphor's optical performance?

The phosphor must be kept sealed, dry, and protected from direct light to prevent moisture absorption and photodegradation. During transfer, minimize airborne dust and use suitable laboratory protective equipment. Atomfair also offers sealed, moisture-resistant packaging tailored to the optical grade and particle-size requirement, which should be specified during quotation.

This research-grade blue-green-emitting oxynitride phosphor (AF-ONBG500) delivers a 495–505 nm emission peak under 440–470 nm excitation, with defined CIE coordinates (x: 0.247–0.264, y: 0.515–0.535) and a quantum efficiency range of 60–80%. The specified median particle size (8–25 µm) supports integration into high-power full-spectrum or specialty lighting, though the powder requires sealed, dry, light-protected storage and careful handling to minimize airborne dust.

Positive

  • Defined blue-green emission range: Emission peak between 495–505 nm with specified CIE chromaticity coordinates (x: 0.247–0.264, y: 0.515–0.535) enables predictable spectral contribution for full-spectrum and monochromatic lighting applications.
  • Controlled particle size distribution: Median particle size (d50) of 8–25 µm provides a defined physical-processing range suitable for slurry formulation, coating, or encapsulation in LED packaging.

Trade-offs

  • Strict storage and handling requirements: The phosphor must be kept sealed, dry, and protected from direct light; airborne dust must be minimized during transfer, requiring appropriate laboratory protective equipment and safety documentation review.
  • Quantum efficiency variability: Quantum efficiency is specified as a range (60–80%), meaning actual performance per batch may vary; users should verify lot-specific efficiency for applications requiring tight optical tolerances.
