The Molybdenum Disulfide–ZnCdSe/ZnS QD-based photodetector response time was reduced to 0.3 s from 15 s for Molybdenum Disulfide layers, making the hybrid device 50 times faster. The schematic of the Molybdenum Disulfide–ZnCdSe/ZnS QD interface and their energy diagram depict the transfer of electrons from ZnCdSe/ZnS QDs to Molybdenum Disulfide layers via a tunneling process and the transfer of excitons from ZnCdSe/ZnS QDs to the Molybdenum Disulfide layer via nonradiative energy transfer (NRET) processes after a heterojunction formation. In the NERT process, the Molybdenum Disulfide layer acts as an acceptor, whereas the ZnCdSe/ZnS QDs thin layer acts as a donor. The photoresponsivity of the hybrid Molybdenum Disulfide–ZnCdSe/ZnS QD-based photodetectors increased by three orders of magnitude to 3.7 × 104 A W−1 compared to pristine Molybdenum Disulfide layers of 10 A W−1. Likely, the detective of the Molybdenum Disulfide–ZnCdSe/ZnS QD-based photodetector increased to 1.0 × 1012 Jones. The gain increased by five orders of magnitude to 1.08 × 105 after adding a layer of QDs due to the increased absorption and efficient energy transfer from the photoexcited ZnCdSe/ZnS QDs layer to Molybdenum Disulfide layers. The better performance of the 2D–0D hybrid photodetector is associated with high carrier mobility in the Molybdenum Disulfide layer and the creation of effective photon absorption/exciton in the ZnCdSe/ZnS QDs layer. The Molybdenum Disulfide layers efficiently quench the fluorescence of the ZnCdSe/ZnS QDs in the 2D–0D hybrid nanostructures exhibiting ultrasensitivity and high gain.
