Pigmenty (Bi2O3)0.7(Ln2O3)0.3, kde Ln = Eu, Gd, Tm, Yb a Lu, byly připravovány klasickou suchou cestou. Připravené práškové materiály poskytovaly světle žlutou až oranžovou barvu. Remisní křivky dosahují vysokých hodnot odrazivosti v rozsahu 600 -700 nm.	oxid vizmutitý;barevné pigmenty;bismutité pigmenty
eng	The effect of lanthanides on colour properties of the (Bi2O3)0.7(Ln2O3)0.3 compounds	(Bi2O3)0.7(Ln2O3)0.3 solid solutions were synthesized as new inorganic yellow and orange pigments. The pigments were prepared by the solid state reaction of mixed oxides (Bi2O3)0.7(Ln2O3)0.3 of various rare earth cations (Ln = Eu, Gd, Tm, Yb and Lu). All the synthesized pigment samples were found to have colour coordinates, low a* and high b* and exhibit the colour from pale light yellow to orange. Reflectance spectra of the samples show high reflectance percentage in the 600 - 700 nm range.	Bismuth(III) Oxide;Colour Pigments;Bismuth Pigments
