Vertically aligned ZnO nanorods synthesized using chemical bath deposition method on seed-layer ZnO/polyethylene naphthalate (PEN) substrates

Fabrication, characterization of ZnO nanorods on the flexible substrate (Kapton tape) via chemical bath deposition for UV photodetector applications

“…Among different oxide compounds, ZnO nanostructures comes a wide attention because of their unique properties and significant for large domain of nanotechnology implementation such as UV photodetectors, light emitting diode (LED), pH sensor, biosensor and chemical sensor [3]. Zinc oxide with a large and direct band gap of 3.37 eV and wide exciton binding energy of 60 eV at room temperature are deem the highly sensitive and most promising materials for sensors because of their slow electron/hole recombination rate, faster response, higher optical gain, high surface-to-volume ratio and specific crystalline orientation [4]. There are different experimental techniques to fabricate the ZnO nanorods such as thermal evaporation [5], filtered vacuum arc deposition (FVAD) [6], metal organic vapor phase epitaxy [7], pulsed laser deposition [8], vapor transport deposition [9], electrospinning [10] and metal organic chemical vapor deposition [11] etc.…”

Effect of Ga-modified layer on flexible hydrogen sensor using ZnO nanorods decorated by Pd catalysts

“…Many approaches have been proposed and developed for the deposition of ZnO films on polymer substrates, such as radio-frequency (RF) magnetron sputtering [3,13], pulsed laser deposition (PLD) [14], dual plasma-enhanced metal-organic chemical vapor deposition (DPEMOCVD) [15], ion-exchange techniques [11], solution-based methods [16][17][18], and chemical bath deposition (CBD) [19]. Several groups developed ZnO nanorods (NRs) on flexible substrates via a seed layer such as ITO-coated PET [18,20] and ZnO-seeded PET [17,19].…”

“…Several groups developed ZnO nanorods (NRs) on flexible substrates via a seed layer such as ITO-coated PET [18,20] and ZnO-seeded PET [17,19]. Further, the effects of processing conditions such as concentration of the precursors [18], deposition time [16,17], sputtering conditions [13], as well as structural [17,18,20] and optical properties [17,20] were also investigated.…”

Development of printed sensors for taste sensing

“…High bendability, high mechanical and thermal resistance and good solvent resistance are some of its advantages due to which it was preferred over other common flexible substrate materials like PDMS [22], PET [23], PEN [24]. Graphene was used as the conductive material to develop the electrodes.…”
