Study of Size Controllable Synthesis of Indium Tin Oxide Nanoparticles and Their Different Characterizations
Abstract: Nanocrystalline indium oxide powders were prepared by combustion synthesis. The changes of nanostructure caused by material processing were studied using X-ray powder diffraction (XRD), transmission electron microscopy (TEM), selected area electron diffraction (SAED) and Brummer Emette teller analysis (BET). The stoichiometric composition of the starting indium tin oxide powder (cubic in traces) induced phase transitions to high temperature. We found that the phase transition to ITO was initiated at the …

Comparative Study of Structural and Optical Properties of Bismuth Ferrite Nanoparticles for Photovoltaic Applications Synthesized via Different Sol-Gel Methods
Abstract: Pure multiferroic bismuth ferrite (BiFeO3) nanoparticles were successfully synthesized using an energy-efficient, low-temperature sol-gel method, comparing two distinct approaches: auto-combustion and non-auto-combustion. To ensure phase stability, the precursor solution's pH was strictly maintained between 1 and 2 using ammonia solution (NH4OH), while ethylene glycol (C2H6O2) was employed as a chelating agent for the Fe3+ and Bi3+ cations. All samples underwent a final annealing process at 500 °C to promote crystallization. …
