A new efficient phosphor, A 9 B(VO 4 ) 7 [A = Ca, Sr, Ba and B = La, Gd] has been synthesized by the solid‐state method at high temperature. X‐ray diffraction analysis confirmed the formation of the compound. Photoluminescence excitation measurements show that the phosphor can be efficiently excited by near‐ultraviolet light from 300 nm to 400 nm to realize emission covering the 397–647 nm region of visible spectrum. Therefore, newly synthesized novel phosphor may be useful as green‐emitting phosphor in solid‐state lighting. Copyright © 2012 John Wiley & Sons, Ltd.
