Summary: The study investigated the structural, morphological, photoluminescence, and UV sensing properties of pure and Tb-doped NiO thin films coated on glass substrates using a cost-effective nebulizer spray technique. The structural studies confirmed a polycrystalline cubic structure with (111) preferred orientation. The photodetector performance of the films was improved by Tb doping, with a decrease in bandgap values and improved rise and decay times observed.

Summary: In this study, indium-doped vanadium pentoxide thin films were prepared with different doping levels using the spray pyrolysis technique. The introduction of indium led to a more disordered structure, smaller crystallite size, increased transparency, and a blue shift in band gap energy. The films were found to be n-type semiconductors, with decreased electron concentration and increased resistivity upon indium doping.

Summary: CuO-based thin films doped with varying Ce concentrations were prepared using chemical spray pyrolysis. The doping of Ce led to modulation of the bandgap and successful substitution of ions in the CuO matrix. The morphology of the films changed with increasing Ce doping. The 4% Ce thin film showed the highest gas sensing capabilities for ethanol and exhibited a chemosorption mechanism.

Summary: To ensure safety in using hydrogen energy, highly sensitive hydrogen sensors are needed for early detection of hydrogen leaks. In this study, a low-cost process was used to fabricate PdO-decorated NiO hydrogen sensors capable of detecting sub-ppm H2 concentration. The results show that PdO doping significantly enhances the gas response to H2.

Summary: Nanocrystalline TiO2: Eu3+ thin films were successfully prepared on glass substrate using the spray pyrolysis technique in this study. The films exhibited tetragonal crystal structure with anatase phase, and their optical properties and electrical conductivity were affected by the concentration of Eu3+ dopant. SEM analysis showed irregular and spherical shaped grains covering the substrate surface, with the films displaying porous nature and an enhancement in photocatalytic degradation with increased Eu3+ concentration.

Summary: Ammonia (NH3) production, storage, and transportation are susceptible to leaks, posing risks to the environment and human life. Detecting NH3 within the exposure limit is crucial for eliminating health hazards. Thin films of zinc ferrite (ZF) were deposited using spray pyrolysis at different substrate temperatures. The film deposited at 225 degrees C showed a good sensing response to 25 ppm of NH3 and exhibited stability over 90 days. This research demonstrates that ZF thin films can effectively detect NH3 in the environment.

Summary: This study investigates the effect of annealing on the physical properties of Co-doped ZnO thin films. The Co doping level is fixed at 10 wt% and the films are deposited using spray pyrolysis techniques. Annealing at different temperatures is conducted and the physical properties are analyzed using various techniques. The results reveal changes in crystallite size, grain formation, band gap value, and plasma frequency, which ultimately affect the performance of the films as UV sensors.
