Towards Evolved Sensing Applications for Organic Photonic Devices Utilizing Room-Temperature Phosphorescence — •Sebastian Kaiser, Sebastian Schellhammer, and Sebastian Reineke — Dresden Integrated Center for Applied Physics and Photonic Materials (IAPP) and Institute of Applied Physics (IAP), Technische Universität Dresden

Photonic devices function through the absorption and emission of light, making them independent of electricity or other influences. This trait is vital for sustainable advances in imaging, sensing, information storage, and anticounterfeiting. Programmable luminescent tags (PLTs) exemplify this by utilizing the oxygen-sensitivity of organic room-temperature phosphorescence (RTP) for controllable switching of the device’s light output under UV illumination. [1, 2]
Optimizing the homogeneity and reproducibility of photonic thin-film devices, paired with use-case-tailored layer compositions, allowed us to develop a new, advanced UV light-sensing application. The thin-film nature of PLTs, especially their flexibility and transparency, combined with a freely scalable sensor area, enables a broader range of use cases than common detectors can achieve. The combination of these unique device characteristics opens the way for new sensing applications for purely photonic devices.
