“…Among existing phosphors with a high optical conversion efficiency and excellent thermal stability, a few red phosphors can be effectively excited using near-ultraviolet (n-UV) light [5][6][7][8]. Eu 3+ can be absorbed in the n-UV and blue regions [9,10]; therefore, Eu 3+ -doped luminescent materials has been widely studied. Desirena et al [11] designed a phosphor for n-UV-based w-LEDs with a low correlated color temperature and a high color rendering index (CRI); a series of highly Eu 3+ -activated tellurite samples were synthesized.…”

This study synthesized BaMoO4:Eu 3+ red phosphors using the microwave method.In addition, the phase composition, morphology, and luminescence properties of the red phosphors were characterized using X-ray diffraction, field-scanning electron microscopy, and photoluminescence spectroscopy. The results revealed that doping red phosphors with different concentrations of Eu 3+ does not change the crystal structure of the matrix material. The BaMoO 4 :Eu 3+ phosphors exhibited micron-scale irregular polyhedra, which could be excited by ultraviolet light with a wavelength of 395 nm to induce red-light emission. The optimal dosage of Eu 3+ was 0.08, and the chromaticity coordinates of BaMoO 4 :0.08Eu 3+ phosphors were (0.5869, 0.3099).White light-emitting diode (w-LED) devices manufactured by using a combination of BaMoO 4 :0.08Eu 3+ phosphor and commercially available phosphors exhibited good white-light emission under the excitation of an ultraviolet chip. The BaMoO 4 :0.08Eu 3+ red phosphors that rapidly synthesized under the microwave field are expected to be used in w-LED devices.
