摘要
We report the photoluminescence characterization of Dy3+-activated NaM4(VO4)(3) (M = Ca, Ba, Sr) phosphors prepared by a solid-state method. The synthesis was confirmed by X-ray diffraction (XRD) characterization and photoluminescence (PL) emission results showed sharp blue and yellow bands for NaM4(VO4)(3) (M = Ca, Ba, Sr):Dy3+ phosphors at the excitation wavelength of 323 nm, which is near-UV excitation. Thus, these phosphors could be applicable for near-UV excited solid-state lighting devices.
