“…5a, the sensor regains its original value of minimum reflectance (R min ) just after removing the target gas (i.e., NO 2 gas) from the gas cell during the recovery cycle. Recently, recent work has been attempted for the same research group, with various metal oxides, dielectric matrix groups, polymerics blended with metals, and SPR-based metals core-shell structures used to detect the different chemical gas vapors (Manikandan et al, 2016;Thanigai Arul et al, 2016;Paulraj et al, 2020;Saasa et al, 2015;Gaur et al, 2021;Paulraj et al, 2021).…”

“…Conductometric gas sensors exploiting semiconductor sensing materials are exclusively used for fabricating gas sensors due to a simple detection principle and easy sensor fabrication (Sharma et al, 2012;Homola et al, 1999;Nikitin et al, 1999;Wilde et al, 1997;Skalska et al, 2010;Dostálek et al, 2006;Kumar et al, 2014;Manikandan et al, 2016;Thanigai Arul et al, 2016;Paulraj et al, 2020;Saasa et al, 2015;Gaur et al, 2021;Paulraj et al, 2021). However, these types of sensors come with a few disadvantages, such as the requirement of a high operating temperature which results in consumption of high power with a poor selectivity.…”

Abstract. In this short communication, we propose a surface plasmon resonance (SPR) sensor based on a ZnO / Au hybrid thin-film material structure and experimentally investigate its sensitivity improvement. The Kretschmann-based SPR sensor utilizes ZnO thin films and nanostructures for performance enhancement. The advancement in SPR technology relies on a low-cost, high-sensitivity, and high-selectivity sensor. Metal oxide (MO) has been incorporated into the SPR sensor to be used for detection of biological and chemical compounds. ZnO as one of the metal oxides is an attractive material due to its unique physical and optical properties. Numerous techniques for fabrication and characterization of ZnO on SPR gold substrate have been studied. The mechanism for gas and biomolecule detection depends on their interaction with the ZnO surface, which is mainly attributed to the high isoelectric point of ZnO. There are several types of ZnO nanostructures which have been employed for SPR application based on the Kretschmann configuration. In the future, the thin film and nanostructures of ZnO could be a potential application for miniature design, robust, high sensitivity, and a low-cost portable type of SPR biosensor to be used for on-site testing in a real-time and label-free manner. The present work includes the application of a developed SPR setup for gas sensing at room temperature using a specially designed gas cell. The change in the optical properties of dielectric layers (ZnO) with adsorption of gases (NO2) in order to develop an optical sensor has been presented. The obtained results emphasize the applications of an SPR setup for the study of interaction of adsorbed gas molecules, with dielectrics and gas sensing.

“…Even some time the intercalated manganese oxide is used in many application as superior agent. The methylene blue intercalated layered MnO 2 nanosheets were synthesized and used (as an efficient electron mediator for the electro-oxidation of the ascorbic acid to dehydro-ascorbic acid) for the fabrication of ascorbic acid sensor [14]. It was suggested that the methylene blue intercalated MnO 2 showed higher electro catalytic activity than non-intercalated MnO 2 .…”

Manganese oxide nanomaterials (Mn3O4) have been prepared from manganese salts of two different anions and studied the role of metal precursor. Manganous sulphate monohydrate and manganese oxalate were used as manganese metal precursors. The obtained Mn3O4 samples were characterized by x‐ray diffraction, transmission electron microscope, Fourier transform infrared spectroscopy, UV‐vis absorbance spectra and photoluminescence excitation spectra. The x‐ray diffraction reveals that the prepared nanoparticles are crystalline in nature with tetragonal structure. In addition, the x‐ray diffraction concludes that the lattice parameters were altered with change in the precursors. The transmission electron microscope exhibits the prepared manganese oxide particles were nano in scale between the ranges of 25 nm to 60 nm. The Fourier transform infrared spectrum confirmed the presence of manganese oxide. The luminescence intensity of the samples varies depending upon the precursors used. The sample comprising of mixed precursors shows higher luminescence intensity than the samples containing MnSO4 ⋅ H2O and MnC2O4 precursors. This is owing to the fact that the surface of the sample has a lower concentration of hydroxyl ions, which was confirmed from the Fourier transform infrared spectra.

A novel, well‐designed, silica‐supported magnesium ferrite nanorods were successfully developed at room temperature using the co‐precipitation method. The synthesized nanorods show an optical band gap of 3.1 eV, with the maximum wavelength absorptive at 334 nm. The average particle size is 36 nm with the FCC crystal structure by the X‐ray Diffraction technique (XRD). TGA achieved thermal stability of targeted mesoporous materials at 600°C. Field Emission Scanning Electron Microscopy (FE‐SEM) and High‐Resolution Transmission Electron Microscopy (HR‐TEM) techniques confirm the rod‐like structure. Energy Dispersive Spectroscopy (EDS) and X‐Ray Fluorescence (XRF) studies reveal the presence of all elements in the composition. The synthesized nanorods are highly magnetic by the vibrating sample magnetometer (VSM) technique, which shows a high coercivity value, that is, MgFe2O4@SiO2 is photocatalytically active. From BET analysis, the surface area, pore volume, and pore diameter are 19.2 m2 g−1, 2.46 cm3 g−1, and 5.10 nm, respectively. The experimental outcomes predict that the degradation efficiency (79%) of methyl orange dye was accomplished using MgFe2O4SiO2 nanorods within 270 min.
