Abstract

This study is focused on the synthesis and characterization of CdNb2O6 compounds doped with of Er3+ ions. Powders were synthesized by using the molten salt method and annealed at 900 degrees C for 4h. The synthesized particles were structurally characterized by using X-ray diffraction, scanning electron microscopy. A single phase of the CdNb2O6 was 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. (C) 2014 Elsevier Ltd. All rights reserved.
