Silver nanowires (AgNWs) are used as transparent electrodes (TE) in many devices. However, the contact mode between is biggest reason why sheet resistance of silver limited. Here, simple and effective ultraviolet (UV) irradiation welding chosen to solve this problem. The influence power density UV on studied fixed time one minute. range (380 nm) from 30 mW/cm2 150 mW/cm2. First all, transmittance nanowire film not found be affected by (400-11,000 nm). decreases 73.9% at 60 increases 127.6%...
First-principles DFT calculations reveal enhanced interaction between non-polar facets of PbS QDs and graphene. External electric fields can modulate energy levels charge transfer, offering insights for optimizing QD/graphene systems.
Dual-band infrared detection offers enhanced spectral information crucial for improved target identification. Traditional dual-band photodetectors have often relied on expensive epitaxial growth bulk materials, limiting their widespread use in civilian applications. Colloidal quantum dots present an affordable alternative detection, owing to tunability and solution processability. In this study, we developed approach utilizing mixed lead sulfide dot films achieve spanning the NIR (Near...
Recently, lead sulfide colloidal quantum dots (PbS CQDs) have demonstrated great potential in becoming one of the promising material candidates for next-generation photodetectors. PbS CQDs provide outstanding properties including size dependent bandgap tunability, high absorption coefficient, solution processability, and multiple exciton generation effects. However, a crucial criterion fabrication high-performance photodetectors is effective surface passivation dots,which can facilitate...

We have successfully developed a high-performance, wide-spectrum TCFs composed of AgNWs and graphene, which undergoes post-treatment through UV welding.
Light loss is one of the main factors affecting quantum efficiency photodetectors. Several approaches have been proposed to mitigate light and improve silicon-based Here, we demonstrate high-sensitivity photodetectors based on highly antireflective silicon nanopillar arrays (Si-NPAs) as a trapping layer combined with thin film silver nanowires (Ag-NWs) in mesh configuration. This composite structure overcomes weak absorption severe surface complexation conventional Introduction Ag-NWs...
HgTe CQDs with tailored shapes (tetrapods, triangles, and distorted parallelograms) were successfully synthesized employed to create vertical-structured broadband photodetectors.
Abstract Quantum dots (QDS) are widely used as photoactive materials for various optoelectronic applications, such light-emitting diodes, photodetectors, lasers, and solar cells, because of their unique outstanding physical properties fabricating devices via solution-processing techniques varying the sizes QD to modulate band gap.
