摘要

近红外上转换发光器件作为新红外成像技术的未来选择具有重要的研究意义。近红外上转换发光器件由光探测单元和发光单元组成,可将人眼不可视的近红外光转换为可见光,其探测波长受到光探测单元限制。本论文研究制备了1550nm近红外波段的有机上转换发光器件,实现了5.77%的功率转换效率。

Abstract

Near-infrared upconversion light-emitting devices have important research significance as the future choice of new infrared imaging technology. The near-infrared upconversion light-emitting device is composed of a light detection unit and a light-emitting unit, which can convert near-infrared light that is invisible to the human eye into visible light, and its detection wavelength is limited by the light detection unit. In this work, an organic near-infrared upconversion light-emitting device capable of detecting the 1550nm near-infrared band was prepared and achieved a power upconversion efficiency of 5.77%.

Key words: Upconversion; Near-infrared; Light-emitting diode; Upconversion efficiency
