Abstract

SnO2 represents an n-type semiconductor possessing a substantial wide band gap of 3.6 eV at room temperature, along with excellent optical and electrical characteristics such as distinctive optical transparency, low resistivity, and a high theoretical specific capacity. The hydrothermal method, employing an aqueous solvent as the reaction medium, stands out for its environmental friendliness since it conducts reactions within a closed system. The XRD pattern aligns with the tetragonal (rutile) phase of the SnO2 crystal structure, as validated by the JCPDS data 411445 and 88-0287. Notably, agglomerations in nanoparticles result in irregular sample morphology. This is further evidenced by SEM, where it is distinctly observable that the average particle size has increased.

Keywords
