Abstract

This study is focused on the synthesis and characterization of CdNb₂O₆compounds doped with of Er³⁺ions. Powders were synthesized by using the molten salt method and annealed at 900 °C for 4 h. The synthesized particles were structurally characterized by using X-ray diffraction, scanning electron microscopy. A single phase of the CdNb₂O₆was determined and the size of the particles was found to be affected by the presence and the concentration of Er³⁺ions. Luminescence properties of each sample were investigated by measuring accurately the emission and excitation spectra at room temperature in the wavelength range of 200-1700 nm by exciting the Er³⁺ions at 379 nm and 805 nm. Quenching of the luminescence in both visible and near infrared spectral regions was observed to be above 1.0 mol% Er³⁺concentration.
