Abstract

A blue silicate, cuprorivaite (CaCuSi4O10), with strong conversion of visible input to infrared emission at around 910 nm, was previously demonstrated for use as a micron scale powder for latent fingerprint imaging. In this research, we prepare a cuprorivaite powder and subject it to mechanochemical treatments that organically modify and exfoliate the material to produce a pigment ideal for ink formulation. The prepared ink was then used to print a security feature.
