摘要：
The n-type zinc oxide (ZnO) colloidal quantum dots (CQDs) and p-type blended poly(9,9-dioctylfluorene-alcohol-benzothiadiazol) (F8BT):6,13-bis (tri-isopropyl-silylethynyl) pentacene (TIPS-P) nanocomposite-based heterojunction fabricated on indium tin oxide (ITO)-coated substrate are explored for ultraviolet (UV)-visible photodetection. The effect of MoO3 hole-transporting layer (HTL) on the performance of the proposed ITO/ZnO CQDs/F8BT:TIPS-P/MoO3/Ag photodetector structure has been investigated. Under - 1 V reverse bias, the maximum responsivity and specific detectivity were improved in the UV region from 29.60 to 70.20 A/W and from 6.35 x 10(12) Jones to 3.97 x 10(13) Jones at similar to 385 nm (17.43 mu W/cm(2) intensity), respectively, by using the MoO3 HTL in the device. On the other hand, the maximum responsivity and specific detectivity were improved, respectively, from 13.68 to 40.92 A/W and from 2.93 x 10(12) to 2.08 x 10(13) Jones in the visible region at 470 nm (35.94 mu W/cm(2) intensity) due to the use of the MoO3 HTL under - 1 V reverse bias.
