Structural properties of Eu3+ doped Gd2Zr2O7 nanopowders: Far-infrared spectroscopy

The Solution Combustion Synthesis (SCS) method was used to prepare nanopowders of europium doped cubic Gd2Zr2O7 nanopowders. The surface of the samples have been investigated using atomic force spectroscopy (AFM) and far-infrared spectroscopy (FIR). Far-infrared reflectivity spectra of Eu3+ doped Gd2Zr2O7 nanopowders were measured at room temperature in spectral region between 80 and 650 cm(-1). The Maxwell Garnet formula was used to model dielectric function of Eu3+ doped Gd2Zr2O7 nanopowders as mixtures of homogenous spherical inclusions in air. (C) 2017 Elsevier B.V. All rights reserved.
