摘要：

We revisited the vanadium oxide phosphors. AVO(3) (A K, Rb, and Cs) and M3V2O8 (A center dot Mg and Zn) for a revaluation of possibility of these compounds for lighting applications, and the internal quantum efficiency (eta) and luminescent colour properties for AVO(3) (A.K, Rb, and Cs) and M3V2O8 (A:Mg, and Zn) have been presented. The AVO(3) showed the broadband emission from 380 to 800 nm, and the eta for the KVO3, RbVO3 and CsVO3 were 4%. 79% and 87%, respectively. The CIE colour coordinates are located at white region on the chromaticity diagram. The M3V2O8 (A Mg and Zn) also exhibited a quite broadband emission between 410 and 900 nm, indicating yellow luminescent colour. The Zn3V2O8 showed high eta value, 52%. compared to that of the Mg3V2O8 (eta = 6%). This enhancement of eta in the Zn3V2O8 could be due to the increasing exciton diffusion assisted by the hybridizations of Zn 3d and O 2p orbitals for the valence band, and Zn 4s and Ti 3d orbitals for the conduction band.
