Aluminate Phosphor

DL-450UV Blue LED Phosphor for UV LED Chips | 450nm Narrow Band Emission


Product Overview

DL-450UV is a high-quality aluminosilicate blue phosphor specifically designed for UV (ultraviolet) LED chip excitation.      The product emits pure blue light with a peak wavelength of 450 nm under 360–390 nm UV excitation, and appears as a white powder, making it easier to control during the manufacturing process.

DL-450UV features a narrow full width at half maximum (FWHM) of 51.7 nm, providing excellent color purity and color gamut performance.      It is suitable for UV-LED lighting, display backlighting, counterfeit detection, and special lighting applications.

Performance Analysis

📊 Spectral Characteristics

DL-450UV exhibits a typical narrow-band emission spectrum with a peak at 450 nm and a half-peak width of only 51.7 nm.                    This narrow spectral characteristic provides excellent color purity, making it suitable for applications requiring high blue light color gamut.

📉 Particle Size Distribution

The phosphor particles show a concentrated and uniform distribution with D50 controlled at 7 ± 0.5 μm.                    This helps maintain consistent settling behavior during dispensing and mixing, reducing color spots and halos.

Recommended Applications

💡 UV-LED Lighting
