Abstract: Bi<subscript>1-x</subscript>La<subscript>x</subscript>VO<subscript>4</subscript> pigments were synthesized as new environment-friendly inorganic materials, and their color properties were characterized. The Bi<subscript>1-x</subscript>La<subscript>x</subscript>VO<subscript>4</subscript> pigments show brilliant yellow colors, and the most effective yellow hue was obtained for Bi<subscript>0.90</subscript>La<subscript>0.10</subscript>VO<subscript>4</subscript>. Since BiVO<subscript>4</subscript> has been known as an environment-friendly inorganic yellow pigment and La is also a nontoxic element, the Bi<subscript>0.90</subscript>La<subscript>0.10</subscript>VO<subscript>4</subscript> pigment should provide effective alternatives to conventional toxic yellow pigments.
