选用LED激光器评价新型柔性光电探测器性能的研究

Study on the Performance of New Flexible Photodetector with LED Laser

柔性电子学的发展,尤其是柔性可穿戴产品的发展需要我们将硬性基底转换成柔性基底。本文选用水热法在导电玻璃(FTO)上成功制备出微观形貌为三维多孔针状的纳米级别半导体硫化铋薄膜,以该材料为原料,首次制作成功一种新型的高性能柔性光电探测器。该柔性光电探测器显示对于450 nm和650 nm激光谱线具有线性光电流特性和高稳定性。该柔性光电探测器具有高柔性,较小的质量,优异的响应特性和对弱激光束极强的敏感性,在新一代柔性可见光光电子器件领域具有非常大的应用前景。

Development of the flexible electronics,especially wearable electronic devices,put forward new requirements for flexible substrates and sensing materials.Herein,using FTO substrate and porous Bi2S3nanoneedles films,the high performance flexible photodetector is successfully fabricated.The photodetector has a fast response to 450 nm and 650 nm laser beams.The photodetector has high flexible,low weight,fast response speed and good sensitivity to weak laser.Our results imply that the new type of photodetector is prospective candidate for next high-performance generation flexible optoelectronic devices.
