Properties of Silver Nanowire/Zinc Oxide Transparent Bilayer Thin Films for Optoelectronic Applications

Abstract

We have investigated electrical, optical and structural properties of silver nanowire (AgNW)/zinc oxide (ZnO) transparent conductive bilayer films for optoelectronic applications. The AgNW/ZnO transparent conductive bilayer films were fabricated using spin-coating and facing target sputtering (FTS) method. The spin-coated the AgNW layer has advantages, such as low resistivity and high transmittance in visible range. However, the spin-coated AgNW layers can be oxidized by natural oxygen. Consequently, the conductivity of AgNW layer was strongly decreased. So, an oxidation prevented layer is necessary. The ZnO thin film layer on the Ag NW layer can be prevented oxidation. In addition, the peeling of spin-coated AgNW layer were prevented the deposited ZnO thin film layer. As the results, the sheet resistance and average transmittance in visible range of AgNW/ZnO transparent bilayer thin films exhibited 34.1 ohm/sq. and 83.46%.

Large-Scale Preparation of Silver Nanowire-Based Flexible Transparent Film Heaters by Slot-Die Coating

“…As reported, silver nanowires (AgNW) are considered to be a favorable material to replace ITO because of their high conductivity, high transparency, suitability for printing, and flexibility [ 15 , 18 , 19 ]. At present, AgNW-based TCFs can be fabricated through conventional preparation techniques, such as vacuum filtration [ 20 ], spin-coating [ 21 , 22 ], drop coating [ 23 ], spray-coating [ 24 ], Mayer rod coating [ 25 , 26 ], and screen printing [ 27 , 28 ]. However, these conventional preparation methods are difficult when taking into account the conductivity and transmittance of AgNW-based TCFs simultaneously, and it is also difficult to achieve large-scale preparation of TCFs, which limits the application of AgNW-based TCFs.…”

AC – Conductivity Study of CdSe Nanorods

“…1D semiconductor nanostructures have been the subject of numerous research activities and have been used to realize prototype electrical and optical test beds [4][5][6][7][8][9][10][11]. Recently the preparations of nanorods and nanowires with axially and radially modulated compositions have been fabricated by various methods [12][13][14][15][16][17]. Inorganic nanorods have a strong tendency to aggregate in the solid state, and CdSe nanorods have been shown to exhibit liquid crystal phases in concentrated solutions, or when cast from solution onto a substrate [18][19][20][21].…”
