On the way to sustainable photoluminescent tags — •Heidi Thomas, Shuaifei Zhu, Sebastian Schellhammer, and Sebastian Reineke — IAPP, TU Dresden

Recently, by using amorphous purely organic systems, we have been able to develop transparent programmable luminescent tags (PLTs) which can be used for labelling application or data storage [1,2]. So far the system consists of a phosphorescent organic emitter embedded in poly(methyl methacrylate) on quartz substrate or flexible foil. An oxygen-blocking layer allows for the spatial control of the phosphoresence of the system. The demand for sustainable solutions is high motivating the design of ecofriendly information storage. Here we present the investigation of suitable biocompatible and/or biodegradable polymers and emitters for their use in PLTs.
