"In this work we have studied the colour properties of the Bi2O3-Ln2O3 system. We have prepared by solid state reaction the mixed (Bi2O3)1-x(Ln2O3)x, where Ln=Er and Ho, with nominal composition x=0,1, 0,3 and 0,5 and calcination temperature 800 \u00B0C. The structure of the prepared compounds was studied by X-ray diffraction analysis. The obtained orange oxide pigments present f.c.c. fluorite-type structure. Colour properties measured in the visible region of light (400 - 700 nm) with Miniscan (Hunter Lab, USA) and indicate that the pigments can be expected as new ecological inorganic pigments."@en .
