Abstract:
YVO4:Tm3+ phosphors have been prepared by solid state reaction method and other chemical methods using high purity chemicals of Y2O3, V2O5 and Tm2O3. The synthesized materials were characterized by X-ray diffraction, scanning electron microscopy, excitation and emission measurements. The upconversion luminescence properties of Yb3+ and Tm3+-codoped YVO4 phosphors also has been investigated in the present work. The results are discussed in comparison with similar reported works.
