摘要

Organic light-emitting diodes (OLEDs) have been the subject of intense research for the past two decades, aiming for display, lighting, and other applications almost exclusively in the visible region. Recently, near-infrared (NIR) OLEDs have received growing interest because of their potential applications in optical communication, night-vision readable displays, and sensors. The materials that are able to show detectable NIR electroluminescence (EL) include mainly rare-earth (lanthanide) complexes, organic dyes, transition-metal complexes, and low band gap polymers. OLEDs based on rare-earth complexes have shown NIR ELatanumberofimportantwavelengths (e.g., 890,977,1064,1346, and 1560nm). Suzuki et al. used ionic dyes in the OLEDs that displayed the EL spectra at around 1100 nm with an optimized external quantum efficiency (EQE) of 0.036%. The LED devices based on low band gap polymers were also reported to emit at approximately 1000 nm, and have an EQE of 0.03-0.05%.
