Abstract

Optical upconverters that convert near-infrared (NIR) light into visible light by directly connecting organic photovoltaic (OPV) devices and organic light-emitting diodes (OLEDs) in series are attracting attention for their potential applications in medicine, night vision, security, and detection. The use of organic system materials eliminates the need for NIR Si integrated circuits and removes limitations on substrate types. The high performance of organic compounds, combined with the manufacturing flexibility of OLEDs, simplifies the production process and reduces costs. The color of the upconversion electroluminescence spectrum can vary across the visible region, from blue to red. Our device achieved a maximum luminance greater than 100cd/m² of green light at 8.5V when illuminated by an 840nm NIR light (1 mW/cm²), and the device reaches an infrared-to-visible upconversion efficiency of 7.23%.
