Abstract :

Tin dioxide (SnO2) nanoparticles were successfully synthesized visa sol–gel technique at 80oC for 1hr. The samples were annealed at 100oC and 300oC for 2hr. The properties of the synthesized samples were investigated using XRD, EDX, SEM, and UV–VIS spectrophotometer. The XRD studies revealed well crystallized tetragonal SnO2 with particle size of 3.0822 nm. Optical analysis showed that the nanoparticles have wide band gap (3.85 eV). The SnO2 synthesized could find applications in gas sensors, microelectronics and solar cells.
