Synthesis and photoluminescence properties of a new red emitting phosphor: Ca3(VO4)2:Eu3+; Mn2+

Abstract A new red emitting phosphor, Ca 3 (VO 4 ) 2 :Eu 3+ ; Mn 2+ , was synthesized by a citric acid sol–gel combustion method and characterized by XRD, TEM and photoluminescence (PL) spectra. The red emission located at about 613 nm was ascribed to 5 D 0 – 7 F 2 transition of Eu 3+ . And the red luminescence intensity changed with annealing temperature and concentration of Eu 3+ . The effect of the co-doped Mn 2+ was also investigated systematically.
