Special Issue Information

Dear Colleagues,

Organic optoelectronic materials offer unprecedented opportunities for the development of devices with functionalities such as detection, light emission, and upconversion due to their fascinating advantages, which include their low cost, lightweight, mechanical flexibility, and biocompatibility. Over the past few decades, organic photodetectors, electroluminescence displays, and upconverters have garnered significant attention; in addition, notable advancements in both the properties of organic semiconductor materials and device architecture engineering have been witnessed. It is undoubted that comprehensive reviews of previous studies and further innovative optimizations of organic optoelectronics are critical for scientific research and societal progress, encompassing diverse applications in areas such as biology, defense safety, space science, wearable electronics, and smart cities.

This Special Issue aims to gather summaries of recent and noteworthy studies and track the latest research in the rapidly evolving field of organic optoelectronics. The scope of this Special Issue includes, but is not limited to, the synthesis and modification of organic semiconductor materials, the analysis and exploration of operational mechanisms, and the optimization and design of devices for applications such as detectors, light-emitting diodes, and upconverters. Contributions to this Special Issue can take the form of original research articles or comprehensive reviews that highlight breakthroughs in fundamental scientific research and technological advancements for industrial applications.

We look forward to receiving your contributions.

Organic upconversion devices (OUDs) are a class of technology that convert low-energy infrared (IR) photons into high-energy visible photons, offering extensive application prospects in fields such as bioimaging, photovoltaics, and display technologies. In recent years, organic materials-based upconversion technology has attracted considerable attention and research interest due to its unique advantages in molecular design, material diversity, and flexible device fabrication. An up-conversion imager consists of the organic photosensitive layer as the sensitizer which is used for absorbing infrared light and the active layers of the organic light-emitting diodes (OLEDs) as emitters which are used for displaying visible light. Under the effect of their common, the incident IR light is converted to visible light. Here, we review the recent progress in the field of organic upconversion materials, explain their performance and characterization, and discuss the challenges and prospects. Full article
