Abstract
A simple and cost-effective salt synthesis route toward refractory oxides of composition Sr 2Ga1-xCoxNbO6 has been carried out. Herein, we report on the refinement of the set of parameters related to heat treatment to stabilize the ordered perovskite for cobalt content, x, ranging from 0.02 to 0.2. The parameters studied were the nature of the flux, the dwell temperature, the dwell time and the cooling rate for a given cobalt precursor. Our study relied on powder X-ray diffraction, UV–visible-near IR (UV–vis–NIR), Electron Spin Resonance (ESR) and Nuclear Magnetic Resonance (NMR) experiments allowing us to better understand the room temperature electronic structure. The tuning of energy gap with the cobalt content, mixed spin state Co3+ (Low Spin + Intermediate/High Spin) at room temperature and the brown shades of these materials render them the multifunctionality.
