Project Details


Current security labelling technologies using pattern coding (“barcoding”) and/or UV-excited phosphorescent inks are relatively easily counterfeited. The project aims to identify optimal design, fabrication and surface treatment of infrared-excited lanthanide nanoparticles for use as pigments in UV-curable polymer inks. This is expected to result in a new-generation of jet-printable security inks with ultimate capability for multidimensional coding (using multiple luminescence wavelengths and lifetimes) and robust readability. Expected outcomes are world leadership in codable inks for secure labelling against counterfeiting, greatly enhancing both global ink-product sales and the value of Australian exports subject to product substitution.
