In this work, we report an ultrasensitive hydrogen (H2) sensor based on tungsten trioxide (WO3) nanorods decorated with platinum (Pt) nanoparticles. WO3 were fabricated by dc magnetron sputtering a glancing angle deposition (GLAD) technique, and decorations of Pt nanoparticles performed normal varying time from 2.5 to 15 s. Crystal structures, morphologies, chemical information Pt-decorated characterized grazing-incident X-ray diffraction, field-emission scanning electron microscopy,...
Herein, we developed a surface-enhanced Raman spectroscopy (SERS)-based aptasensor platform by modifying gold (Au) nanoparticle SERS substrates with thiol-containing aptamer for sensitive and selective detection of paraquat (PQ), commonly used herbicide weed grass control. The Au substrate in this study is commercial (ONSPEC-Lite, https://www.nectec.or.th/en/innovation/product-innovation/onspec-series.html) our group at NECTEC, Thailand. average size the 59 ± 17 nm. A thiol-modified PQ77-SH...
Tungsten oxide films (WO3) were deposited on ITO/glass substrates with tungsten target in UHV by d.c. reactive magnetron sputtering. The WO3 at various O2 flow rates from 5 to 20 sccm and film thicknesses 50 500 nm 10 mTorr operating pressure as controlled control gate valve. influence of rate structural, optical electrochromic properties investigated. All the found amorphous which indicated X-ray diffraction (XRD). deposition was decreased increasing oxygen rate. constants transmission...
This study systematically investigates the influence of antimony (Sb) species on electrical properties Sb-doped zinc oxide (SZO) thin films prepared by pulsed laser deposition in an oxygen-rich environment. The Sb species-related defects were controlled through a qualitative change energy per atom increasing content Sb2O3:ZnO-ablating target. By Sb2O3 (wt.%) target, Sb3+ became dominant ablation plasma plume. Consequently, n-type conductivity was converted to p-type SZO using ablating target...
A nanostructural thin film is one of the highly exploiting research areas particularly in applications sensor, photocatalytic, and solar-cell technologies. In past two decades, integration glancing-angle deposition (GLAD) technique to physical vapor (PVD) process has gained significant attention for well-controlled multidimensional nanomorphologies because fast, simple, cost-effective, mass-production capability. The performance functional properties coated films generally depend upon their...
