We report the photoluminescence characterization of Dy 3+ ‐activated NaM 4 (VO 4 ) 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 NaM 4 (VO 4 ) 3 (M = Ca, Ba, Sr):Dy 3+ 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. Copyright © 2011 John Wiley & Sons, Ltd.
