摘      要：Organic semiconductor materials have shown unique advantages in the development of optoelectronic devices due to their ease of preparation,low cost,lightweight,and *** this work,we explored the application of the organic semiconductor Y6-1O single crystal in photodetection ***,Y6-1O single crystal material was prepared on a silicon substrate using solution droplet casting *** optical properties of Y6-1O material were characterized by polarized optical microscopy,fluorescence spectroscopy,etc.,confirming its highly single crystalline performance and emission properties in the near-infrared *** based on Y6-1O materials with different thicknesses were then fabricated and *** was found that the devices exhibited good visible to near-infrared photoresponse,with the maximum photoresponse in the near-infrared region at 785 *** photocurrent on/off ratio reaches 10^(2),and photoresponsivity reaches 16 mA/*** was also found that the spectral response of the device could be regulated by gate voltage as well as the material thickness,providing important conditions for optimizing the performance of near-infrared *** study not only demonstrates the excellent performance of organic phototransistors based on Y6-1O single crystal material in near-infrared detection but also provides new ideas and directions for the future development of infrared detectors.
