Zinc oxide films with different average grain size are deposited on glass substrates by spray‐pyrolysis at 425 °C. Samples characterized XRD, UV–Vis transmittance, FE‐SEM, and electrical properties measurements. The increase in conductivity observed under 365 nm wavelength illumination is evaluated terms of size. Films small grains (120 nm) show higher response respect to larger (230 300 nm). A model considering resistivity for the prediction UV‐to‐dark ratio proposed validated experimental results.
The development of sensors that can monitor ultraviolet radiation has many implications for daily life, and even more so if the focus is on low-cost solution processes use eco-friendly materials. In this study, we produced a UV-sensor based Sn-doped ZnO thin films grown by spray pyrolysis, with doping content ranging from 1 to 10 at.%. study focuses characterization device, their potential UV detection. Structural analysis via XRD, FESEM, STEM confirms polycrystalline nature films, hexagonal...
Resumen: Electrolitos poliméricos conductores de iones litio, basados en alcohol polivinilo (PVA-OH) complejado con la sal Li 2 SO 4 y diferentes relaciones porcentaje peso plastificante PEG 400 fueron preparados por técnica solución utilizando agua desionizada como disolvente.El estudio FTIR confirma formación del complejo polímero-sal.Las curvas descomposición térmica obtenidas termogravimetría (TGA) muestran que estabilidad los electrolitos depende plastificante.Un proceso relajación es...
Transparent films based on Ti, Sn and Zn oxides are of great importance in electronic devices such as sensors, solar cells conductive films, then the characterization techniques highly relevant. The aim this work is to identify advantages disadvantages direct methods, profilometry, indirect methods ellipsometry spectrophotometry used quantify film thickness. In work, were deposited by spray-pyrolysis glass substrates at 425±C. Thicknesses varied between 150 300 nm. calculated means...
