Abstract

Nd-doped SrNb₂O₆ particles have been prepared by a molten salt method using strontium nitrate, niobium oxide and NaCl-KCl salt mixture as a flux at a relatively low temperature as compared to solid-state reaction method. X-ray diffraction patterns of the pure SrNb₂O₆ samples exhibited a single orthorhombic phase. Photoluminescence (PL) properties of Nd-doped samples in near-infrared spectral region were studied in detail. A characteristic luminescence of Nd³⁺ at 1.06 μm was observed for Nd-doped SrNb₂O₆. Concentration quenching phenomenon was detected depending on the Nd-doping concentrations at room temperature. This characteristic of the doped samples may be ascribed to the energy transfer between Nd³⁺ and niobate groups (NbO₆).
