中文摘要: 光电探测及信息显示技术是实现信息传输、信息处理和信息转换的关键性技术。本项目提出一种红外探测显示的信息处理器件,即将红外光经过光-电-光过程转换为可见光,从而实现红外光传感的器件。 基于无机近红外波段探测单元(PD)与有机电致发光显示单元(OLED)集成耦合的光传感器件结构,充分利用无机探测的高响应度和OLED的材料选择多样性、温度使用范围广、成本低等优势,高效地实现红外光的上转换。主要利用分子束外延(MBE)和有机分子束沉积(OMBD),以及半导体工艺技术等方法设计和制作原型红外光传感器件,研究有机-无机界面处载流子注入等工作原理,以求获得较好的器件性能,尤其是光-光转换功率效率。我们拟选择n型注入为切入点,研究探测器与OLED之间的n型界面层、钝化层以及OLED的半透明阳极等方面,探讨探测器响应度等参数与最终光转换器件性能之间的关系,为下一步实现中远波段红外光转换奠定基础。

The project proposed an infrared detection and display information processor, which infrared light is converted to visible light through the optical-electrical- optical process. This kind of infrared light sensor instructure integrated the inorganic near-infrared detection unit (PD) and organic light-emitting display unit (OLED)to achieve infrared light upconversion effectively. It take full advantage of the inorganic detection of highly responsiveness and OLED of material flexibility,wide temperature range, low cost. By molecular beam epitaxy (MBE), organic molecular beam deposition (OMBD), and semiconductor process technology, we design and make a prototype infrared light sensor, then study the working principle of organic-inorganic interface of carrier injection, in order to obtain better device performance, especially in light - light power conversion efficiency. We intend to select the n-type injection as the starting point to investigate the n-type interface layer between the detector and the OLED, the passivation layer and the OLED translucent anode.It is important to explore the relasionship between detector performance, such as device responsiveness and final perfo
