Abstract
Abstract The cation substituted Tutton's salt single crystals were obtained with empirical formula K2NixCo1-x(SO4)2•6H2O and K2NixMg1-x(SO4)2•6H2O (x = 0, 0.2, 0.4, 0.6, 0.8, 1.0). All crystals were grown by slow evaporation technique and investigated by X-ray powder diffraction, differential thermal analysis, UV–VIS–NIR, and atomic absorption spectroscopy. Combination of differential thermal analysis (conducted in 25–840 °C temperature range), X-ray powder diffraction and mass loss measurement adds information about thermal stability and phase composition at different temperatures. The optical characteristics such as transmittance and optical energy gap of the grown crystals were determined. Established, that K2Ni0.4Co0.6(SO4)2•6H2O crystals has a highest dehydration temperature (137 °C), band gap energy (6.49 eV) and transmittance in UVB region.
