Synthesis of Persistent Luminescent Nanoparticles for Rewritable Displays and Illumination Applications

Our research focuses on developing functional nanomaterials. Based on precise biotechnology, we aim to achieve bioimaging, disease treatment, and physiological function regulation in a minimally invasive and highly selective fashion by using nanocomposites with luminescence, thermal, magnetic, and acoustic properties. We have demonstrated that utilizing a rigid backbone chain polymer, polymethyl methacrylate as the matrix, purely polycyclic aromatic hydrocarbons can exhibit stable and exceptionally long phosphorescent lifetimes, showcasing purely organic, room temperature phosphorescent properties.

We expect that this protocol not only provide a detailed experimental procedure for the hydrothermal synthesis of long-lasting imaging nanomaterials, but also introduce a method for the co-polymerization of persistent luminescent nanoparticles and MMA to further achieve ultraviolet mediated rewrite and luminescent applications. The hydrothermal synthesis masses of persistent luminescent nanoparticles could restrict the application of certain temperature sensitive substance, since they require relatively high reaction temperatures. Consequently, the selection of appropriate synthesis methods should be contingent on specific application and requirement.
