发展了一种新的简便的溶液法合成高质量的CuInSe 2纳米晶，具有单分散的尺寸和均匀的六边形形状。基于CuInSe 2纳米晶和聚3-己基噻吩的杂化薄膜，构建了一种高性能的杂化光电探测器。该器件显示出不同的“开”和“关”状态，响应于外部照明的光电流的比率>100。该杂化器件的高灵敏度和稳定性为杂化材料在光探测和信号放大领域的应用提供了广阔的前景，有利于大面积、低成本、轻量化和可折叠产品的开发。
A new facile solution method for the synthesis of high-quality CuInSe2 nanocrystals with monodispersed size and uniform hexagonal shape was developed. A high-performance hybrid photodetector based on a hybrid film of CuInSe2 nanocrystals and poly(3-hexylthiophene) was constructed. The device showed distinct "ON" and "OFF" states with a ratio of >100 in photocurrents responding to outside illumination. The high sensitivity and stability of the hybrid device revealed a broad prospect for use of the hybrid material in light detection and signal magnification for the development of large-area, low-cost, lightweight, and foldable products.
