In this study, we investigated the surface plasmon resonance (SPR) sensing based on photonic crystal structures which are designed using a single graphene sheet and multilayer metal oxides (Al2O3 and ZnO) for detection sensitivity and the absorption of molecules through excitation wavelength when using air and water as analytes. The refractive index (η) of air is 1.0 and water is 1.33. The method...
Tin doped ZnO (Sn:ZnO) thin films were deposited onto glass substrate using sol-gel spin coating method. The doping concentrations of thin films were varied from 1.0 – 5.0 at. % Tin. The optical and electrical properties of Sn doped ZnO thin films were investigated. The electrical properties were analyzed using I–V measurement (CEP 2400). The optical properties were characterized by ultraviolet visible...
Hierarchical Si/ZnO trunk-branch nanostructures (NSs) have been synthesized by hot wire assisted chemical vapor deposition method for trunk Si nanowires (NWs) on indium tin oxide (ITO) substrate and followed by the vapor transport condensation (VTC) method for zinc oxide (ZnO) nanorods (NRs) which was laterally grown from each Si nanowires (NWs). A spin coating method has been used for zinc oxide...
This experiment has been done to develop the process for synthesizing ZnO nanorods on FTO substrate using hydrothermal growth solution method with two different molarities and to fabricate Interdigital Transducer (IDT) fingers electrode for surface acoustic wave application. The FTO substrate was pre-coated with ZnO nanoparticle seed layer that was prepared by utilizing low cost and low temperature...
