Unveiling unusual coloration in amorphous phosphate pigments: a study inspired by the mineral Brazilianite

Abstract Brazilianite, with the formula NaAl3(PO4)2(OH)4, exhibits an intriguing pale yellow to green coloration, a phenomenon not readily explained by the absence of conventional d-block chromophoric metal ions. This study investigates the synthesis of amorphous phosphate-based pigments composition...
