Abstract
We report a coprecipitation method for the preparation of solid solutions in the Zn2TixSn1–xO4 0 ≤ x ≤ 1 series The precipitates obtained from the coprecipitation were calcined using different temperatures and then characterized with Xray diffraction XRD Raman scattering RS scanning electron microscopy SEM and surface area measurements to gain insights into the solidstate reaction and phase transformation during the calcinations Formation of the Zn2TixSn1–xO4 solid solutions was observed after the calcination up to 1000 °C which is much lower than the temperature 1300 °C required in the conventional solidstate reaction method The optical absorption property of the Zn2TixSn1–xO4 solid solutions measured by ultravioletvisible diffuse reflectance spectroscopy UV–Vis DRS was shown to change according to the composition of the solid solutions
