Investigation of Boron-doping Effect on Photoluminescence Properties of CdNb2O6: Eu3+ Phosphors

Pure, Eu 3+  − doped and Eu 3+ ,B 3+ co-doped CdNb 2 O 6 powders have been prepared by a molten salt synthesis method using Li 2 SO 4 /Na 2 SO 4 salt mixture as a flux at a relatively low temperatures as compared to solid state reaction. X-ray diffraction patterns of pure CdNb 2 O 6 samples indicate...

Summary:Pure, Eu 3+  − doped and Eu 3+ ,B 3+ co-doped CdNb 2 O 6 powders have been prepared by a molten salt synthesis method using Li 2 SO 4 /Na 2 SO 4 salt mixture as a flux at a relatively low temperatures as compared to solid state reaction. X-ray diffraction patterns of pure CdNb 2 O 6 samples indicated orthorhombic single phase. Photoluminescence investigations of CdNb 2 O 6 samples showed a strong blue emission band centered at 460 nm. For Eu-doped CdNb 2 O 6 samples, the luminescence of Eu 3+ was observed with the host red emission varying with the Eu-doping concentrations. This PL characteristic of the doped samples may be attributed to the energy transfer between Eu 3+ and niobate groups (NbO 6 ). Boron incorporation has remarkably increased the luminescence of Eu 3+ -doped CdNb 2 O 6 .
