Abstract

Fe3O4/SiO2 core shell synthesis has been carried out, and its characteristics has been analyzed to be used as a photocatalyst using co-precipitation and sol-gel method. Fe3O4 is used as the core material to eliminate the difficulty of separating the photocatalyst powder from the solution medium, SiO2 is used to avoid oxidation by preventing the Fe3O4 core from coming into direct contact with the solution. The samples were then characterized using X-Ray Diffraction (XRD), Fourier Transform Infra-Red (FTIR), and Vibrating Sample Magnetometer (VSM). The XRD and FTIR results showed that the crystal structure and movement of the sample molecules matched the standard characteristics from previous studies. The VSM characterization results show that SiO2 succeeded in reducing the value of the magnetization of Fe3O4, which proves that Fe3O4 has been successfully coated by SiO2.

Abstract In this study, we have deposited nanostructured ZnO thin films using the Ultrasonic Spray Pyrolysis (USP) method on an Indium Tin Oxide (ITO) glass substrate for 15 minutes at 450℃. Zinc Acetate Dyhydrate [Zn(CH3COO)2] was used as a Zn precursor with various precursor concentrations of 0.1M and 0.4M. The ZnO thin film has been characterized using an X-Ray Diffractometer (XRD), Uv-Vis Spectrophotometer, and Scanning Electron Microscope (SEM) to obtain a crystal structure, absorbance, and morphology structure. Based on the Inorganic Crystal Structure Database (ICSD) number #98-003-1060 and #98-005-7478, the X-Ray Diffraction (XRD) pattern of ZnO thin film has a polycrystalline hexagonal wurtzite structure with space group P63mc. Uv-Vis characterization for samples with a concentration of 0.4M showed that there was an increase in absorbance intensity that was most dominant at ~320 nm. Hence, it can be predicted that the sample has an energy gap of 3.2 eV. Keywords: ZnO thin film, ultrasonic spray pyrolysis, crystal structure, absorbance, bandgap.

Abstract

Surface-Enhanced Raman Spectroscopy (SERS) is a highly effective technique for detecting trace amounts of molecular species. However, the widespread use of conventional noble metal substrates is limited by high fabrication costs and scalability issues. Perovskite materials have recently emerged as promising alternatives, though many are lead-based and pose environmental risks. In this study, we present a lead-free bismuth ferrite (BiFeO₃) perovskite synthesized via the sol–gel method as a novel SERS substrate for the detection of Rhodamine B, a toxic dye commonly used illicitly in food products. Comprehensive characterization using X-ray Diffraction (XRD), X-ray Fluorescence (XRF), and UV-Visible Diffuse Reflectance Spectroscopy confirmed the successful formation of a single-phase rhombohedral structure with a direct bandgap of 2.1 eV, indicating strong visible-light absorption. The BiFeO₃ substrate demonstrated effective SERS performance, facilitating a detection of Rhodamine B at concentrations as low as 10 ppm. These results highlight the potential of lead-free BiFeO₃ perovskites as practical and environmentally friendly alternatives to noble metals for SERS-based detection of hazardous dyes and other environmental contaminants.
