Magnetic Susceptibility of Quasi-One-Dimensional Compound α'- NaV2O5 –Possible Spin-Peierls Compound with High Critical Temperature of 34 K–
Masahiko Isobe,Yutaka Ueda +1 more
TL;DR: In this paper, the magnetic susceptibility of α'-NaV 2 O 5 was measured in the temperature range from 2 K to 700 K and it was shown that below 34 K, the spin susceptibility rapidly decreases with decreasing temperature to a constant value of 1.49×10 -4 emu/V 4+ -mol.

Mixed valency and charge ordering in α'-NaV 2 O 5
TL;DR: In this paper, the phase transition in a spin-peierls (SP) system is not a conventional SP transition but a charge ordering below the transition temperature of the NMR spectra.

Correlation between Luminescence Quantum Efficiency and Structural Properties of Vanadate Phosphors with Chained, Dimerized, and Isolated VO4 Tetrahedra
TL;DR: In this paper, the authors investigated the internal luminescence quantum efficiency and color properties of vanadate phosphors with VO4 tetrahedra, and they found that the long exciton diffusion lifetime induced by these structural features led to high quantum efficiency.

A revisit of photoluminescence property for vanadate oxides AVO3 (A:K, Rb and Cs) and M3V2O8 (M:Mg and Zn)
TL;DR: In this article, the authors revisited the vanadium oxide phosphors, AVO 3 (A:K, Rb, and Cs) and M 3 V 2 O 8(A:Mg and Zn) for a revaluation of possibility of these compounds for lighting applications, and the internal quantum efficiency and luminescent colour properties for AVO3 and M3 V 2O 8 have been presented.

Direct fabrication of metavanadate phosphor films on organic substrates for white-light-emitting devices
TL;DR: The optical properties of white-light-emitting metavanadate phosphors, AVO3, are shown and a new direct fabrication process for RbVO3 films onto flexible polyethylene terephthalate (PET) substrates is reported by means of a vacuum ultraviolet irradiation using an excimer lamp.
