“…To further improve the performance of inkjet printing, ZnO UV photodetector is still a difficult issue. There have been many researches investigated the photodetectors modified by metallic NPs to improve the performance [17][18][19][20][21]. However, none of them has fabricated metallic NPmodified ZnO photodetectors by all-inkjet-printing method and the advantages of inkjet printing cannot be fully utilized.…”

To further improve the performance of all-inkjet-printing ZnO UV photodetector and maintain the advantages of inkjet printing technology, the inkjet printing Ag nanoparticles (NPs) were deposited on the inkjet printing ZnO UV photodetector for the first time. The inkjet printing Ag NPs can passivate the surface defects of ZnO and work as surface plasmons from the characterization of photoluminescence (PL), X-ray photoelectron spectroscopy (XPS), and finite difference time domain method (FDTD) simulation. The normalized detectivity (D *) of the Ag NP-modified detector reaches to 1.45 × 10 10 Jones at 0.715 mW incident light power, which is higher than that of 5.72 × 10 9 Jones of the bare ZnO photodetector. The power-law relationship between the photocurrent and the incident light power of the Ag NP-modified ZnO detector is I pc ∝ P 2.34 , which means the photocurrent is highly sensitive to the change of incident light power.

“…, Ag, Au, Pt, Pd) nanocomposites for plasmon-assisted photocatalysis applications. 80–84 This derives from the optical properties exhibited by these systems, which can be precisely controlled by their morphology and spatial arrangement in the semiconductor matrix. These metallic elements exhibit free electrons in the conduction band, which allows them to present an oscillation response for specific frequencies of the incident electromagnetic field.…”

“…The processes such as doping, composite creation, dye sensitization, and noble metal inclusion are favored techniques for activating photocatalytic materials in the visible region. [28][29][30][31][32][33] Surface plasmon resonance (SPR) behaviour has been found to cause the aforementioned properties in Ag or Au anchored ZnObased heterostructures. 30,33 Aer taking into account all of these parameters, we propose combining all three components (NiO x , rGO, and Ag) to improve photocatalytic activity by lengthening electron-hole pair separation rate and improving visible light area functioning.…”
