Luminescence properties of self‐activated Ca5Mg3Zn(VO4)6 and Ca5Mg3Zn(VO4)6:xEu3+ phosphors

Abstract Self‐activated Ca 5 Mg 3 Zn(VO 4 ) 6 and Ca 5 Mg 3 Zn(VO 4 ) 6 :xEu 3+ phosphors were synthesized via a high‐temperature solid‐state reaction route. The crystalline structure and luminescence properties of the phosphors were analyzed using an X‐ray diffractometer and a photoluminescence spectrometer. The explored results indicated that by varying calcination temperature and the raw material ratio of Ca 2+ /Mg 2+ /Zn 2+ , the phosphors could be developed with different phases, crystallinity, and various fluorescence performances. The fluorescence spectrum of Ca 5 Mg 3 Zn(VO 4 ) 6 showed a broad emission band over the range 400–650 nm under an excitation wavelength of 330 nm, as well as green light emission. Furthermore, after introduction of Eu 3+ ions in Eu(VO 4 ) 4 , the luminescence intensity of the Eu 3+ ions greatly increased as the Eu 3+ ion concentration increased at the 393 nm excitation wavelength, showing green–yellow light emission simultaneously. Therefore, the obtained phosphors could be used as a potential green–yellow‐emitting luminescent material in a white light‐emitting diode device.
