Abstract

A series of novel environmentally inorganic pigments based on Bi2O3 doped by rare-earth elements RE (Er, Ho, La, Nd, Dy, Lu and Y) have been developed and characterized using methods of thermal analysis, X-ray powder diffraction and by reflectance spectral data. The new pigments have been synthesized from mixtures containing Bi2O3 and RE2O3 by traditional solid-state route. The incorporation of RE3+ into crystal lattice Bi2O3 changes the colour from yellow, yellow-orange to orange. The simultaneous TG–DTA measurements were used for determination of the temperature region of the pigment formation and thermal stability of pigments. The results confirm the positive effect of rare-earth ions doped into Bi2O3 that contribute to a growth of thermal stability of prepared pigments.
