Abstract

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.
