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.

使用图案编码（“条形码”）和/或UV激发的磷光油墨的当前安全标签技术相对容易伪造。该项目旨在确定红外激发的镧系元素纳米粒子的最佳设计，制造和表面处理，用作紫外光固化聚合物油墨中的颜料。预计这将导致新一代的喷墨打印安全油墨具有多维编码（使用多个发光波长和寿命）和强大的可读性的最终能力。预期成果是在防伪安全标签的可编码油墨方面处于世界领先地位，大大提高全球油墨产品的销售额和受产品替代影响的澳大利亚出口价值。
