DL-450UV
UV-Optimized Aluminosilicate Blue Phosphor for 360–390 nm UV LED Chips
Product Overview
DL-450UV is a UV-excited blue phosphor engineered for 360–390 nm ultraviolet LED chips. Under UV excitation, it emits pure blue light with a precisely controlled peak wavelength of 450 nm.
The material appears as a white powder under ambient conditions, supporting easier incoming inspection and stable processing. With a relatively narrow emission profile (FWHM 51.7 nm), DL-450UV helps deliver improved color purity for UV-LED lighting, display backlighting, and security verification applications.
