Nitride Yellow-Emitting Phosphor
Research-grade luminescent powder
Product Overview

This nitride yellow-emitting phosphor is a blue-excitable luminescent powder intended for high-power lighting. It provides a selectable yellow-emission band, defined particle-size range, CIE color coordinates and quantum-efficiency range for phosphor-converted illumination.

Key specifications include recommended excitation range: 440–470 nm; emission peak range: 535–550 nm; median particle size (d50): 5–30 µm; cie chromaticity coordinate x: 0.41–0.46; cie chromaticity coordinate y: 0.52–0.56; quantum efficiency: 70–80%. These parameters define the available wavelength, optical-performance and physical-processing range for this product.

The product is intended for High-power lighting. Selection should be based on the required emission wavelength or spectral distribution, excitation source, particle-size requirement where stated, processing method and final application.

This phosphor powder must be stored sealed, dry, and protected from direct light to maintain its optical properties. During transfer, airborne dust must be minimized and appropriate laboratory protective equipment must be used.

  • Storage Conditions: Store the phosphor in a sealed container, away from moisture and direct light, to prevent degradation.
  • Handling Precautions: Minimize airborne dust generation during transfer and wear suitable personal protective equipment as specified in the safety documentation.

What is the quantum efficiency range and emission peak range of the Atomfair AF-NYYEL nitride yellow-emitting phosphor?

The AF-NYYEL phosphor offers a quantum efficiency range of 70–80% and an emission peak range of 535–550 nm. These specifications are explicitly stated in the product datasheet, ensuring predictable optical performance for high-power lighting applications.

Can the AF-NYYEL phosphor be excited by standard 450 nm blue LEDs?

Yes, the recommended excitation range is 440–470 nm, which fully covers the 450 nm blue LED emission. This compatibility is confirmed by the product's specified excitation window, making it suitable for phosphor-converted white light generation.

What handling precautions are required for the AF-NYYEL nitride yellow-emitting phosphor powder?

The phosphor must be kept sealed, dry, and protected from direct light to prevent degradation. Minimize airborne dust during transfer, use suitable laboratory protective equipment, and review applicable safety documentation before handling, as stated in the product's chemical powder handling guidelines.

This nitride yellow-emitting phosphor provides a defined 535–550 nm emission band under 440–470 nm blue excitation, with selectable median particle size (5–30 µm) and specified CIE coordinates and quantum efficiency (70–80%), making it suitable for high-power lighting applications. However, the powder requires sealed, dry, light-protected storage and careful selection of emission wavelength, particle size, and processing method to match the intended application.

Positive

  • Defined yellow emission band: Emission peak range of 535–550 nm with recommended blue excitation of 440–470 nm, enabling precise spectral matching for phosphor-converted high-power lighting.
  • Selectable particle size and optical specs: Median particle size (D50) selectable from 5 to 30 µm, combined with specified CIE chromaticity coordinates (x: 0.41–0.46, y: 0.52–0.56) and quantum efficiency range (70–80%), allowing controlled optical performance and processing compatibility.

Trade-offs

  • Moisture and light sensitivity: The phosphor must be kept sealed, dry, and protected from direct light to maintain performance; airborne dust must be minimized during transfer, requiring appropriate laboratory handling procedures.
  • Application-specific selection required: Optimal use demands careful matching of emission wavelength, excitation source, particle size, processing method, and final application, necessitating technical expertise during specification and quotation.
