1. Influência do contra-íon molibdênio nas propriedades do pigmento SnO2: Cr / Influence of the molybdenum counterion in the properties of SnO2:Cr pigments
SnO2 pigments, when doped with chromium, lead to violet or purple colors, depending on chromium oxidation state. There is a need to control the chromophore oxidation state, as Cr(VI) is toxic and carcinogenic, while Cr(III) leads to no risk to living beings. Cr(VI) formation may be avoided with the addition of counterions, that lead to a charge imbalance. In
