Samples were synthesised by solid-state reaction at high temperatures and characterised by X-ray diffraction analysis, colouristic analysis and particle size analysis. Possible MoO3 evaporation at high temperatures was studied by method of thermal analysis. The most interesting sample is SrO–0.65SnO2–0.05MoO3–0.075Tb4O7 which was prepared by calcination at 1500 °C. This powder is single phase, with cubic structure. Colour of the sample is dark green (L* = 46.37, b* = −9.630 and b* = 10.60).
