Advanced lanthanide-doped nanomaterials for new-generation security inks

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被伪造。该项目旨在确定用于紫外光固化聚合物油墨颜料的红外激发稀土纳米颗粒的最佳设计、制造和表面处理。预计这将导致新一代可喷射打印的安全油墨，具有终极的多维编码能力(使用多个发光波长和寿命)和强大的可读性。预期结果是在用于安全标签防伪的可编码油墨方面处于世界领先地位，极大地提高全球油墨产品销售和澳大利亚出口产品替代产品的价值。

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.
