“…As shown in Figure d, the wurtzite structure of the ZnO HNs can be evidenced by lattice fringes with d -spacings of 0.26 and 0.24 nm, corresponding to the (002) and (101) crystal planes, respectively . The characteristic peaks at 31.6, 34.3, and 36.1° in X-ray diffraction (XRD) spectra correspond to Miller indices (100), (002), and (101) of the ZnO HNs on the AAO substrates, respectively, as shown in Figure e . According to the Bragg law, the lattice constants a and c of wurtzite ZnO lattice constants can be calculated by where λ is the X-ray wavelength (Cu Kα, λ = 1.5405 Å).…”

The dilemma of harvesting fugacious photons by photoactive nanomaterials of limited absorption volume fundamentally hinders the photodetection at relatively lower light intensities. To address the insufficient light utilization efficiency, spatial light confinement becomes an effective and promising approach. High-performance ultraviolet (UV) photodetectors based on the self-assembled Au nanoparticle/ZnO honeycomb nano-mesh (Au NP/ZnO HN) are demonstrated through a facile solution-processed method on anodized aluminum oxide (AAO) membranes. The congregated geometry of the self-assembled ZnO HNs is well-defined by the AAO matrixes, which also effectively collects the transmitted light beams back to the photoactive layers. Benefiting from surface plasmon resonance, the enhanced absorption of the ZnO HNs is eventually obtained via the recursive light utilization between Au NPs and AAO matrixes as a function of AAO pore diameters (D AAO). With a systematic control of the photodetector configurations, an optimal performance is obtained with growth duration of the ZnO HNs for 40 min on the AAO substrates (D AAO = 100 nm), and an excellent responsivity of 23.4 A/W is witnessed even under a relatively low light intensity of 0.4 mW/cm2, providing a novel route to realize high-performance UV photodetection under low-power illumination.

“…Lee and his team have developed CVD-grown bilayer WSe2-based piezoelectric nanogenerators with an output voltage of 85 mV . Similarly, Aminullah et al have fabricated a piezoelectric nanogenerator using 3D-ZnO nanosheets on an anodic aluminum oxide (AAO) membrane with an output voltage of 895 mV and current of 446 nA . The above comparison shows that the output voltage and current of the WS 2 QDs-reinforced PVDF-HFP nanocomposite nanogenerator was several times higher than that of similar reported nanogenerator devices.…”

Herein, we reported the fabrication of a highly flexible, sensitive, lightweight, self-poled, hybrid tungsten disulfide (WS 2 ) quantum dots-filled poly(vinylidene fluoride-co-hexafluoropropene) (PVDF-HFP) nanocompositebased piezoelectric nanogenerator device with high output performance. Highly uniform WS 2 quantum dots with an average diameter of 7−8 nm were synthesized from the hydrothermal route and an enhanced piezoelectric β-phase of PVDF-HFP was obtained through the polar DMF solvent and in situ electrical poling. Structural and morphological investigation revealed the formation of the pure phase of the WS 2 QDs-PVDF-HFP nanocomposite and β-phase of PVDF-HFP. Piezoelectric force microscope analysis revealed a very high piezoelectric charge coefficient (d 33 ) of ∼294.55 pm/V from single WS 2 QDs. The flexible transparent piezoelectric nanogenerator fabricated from the WS 2 QDs-PVDF-HFP nanogenerator produced a remarkably high output voltage and output current density of about 22 V and 1.06 μA/cm 2 , respectively, even under low pressure and without external electrical poling. The WS 2 QDs-PVDF-HFP nanocomposite exhibited a high dielectric constant of 30 at low frequency. The high performance of the nanocomposite nanogenerators was discussed in light of the high piezoelectricity, interface polarization, and large dielectric constant. The present study opens an excellent route to developing a self-powered, ultralight, flexible energy-harvesting system for wearable and body implantable nanodevices.
