Abstract
Nanocrystalline boron doped tin oxide and boron and silver co-doped SnO2 was successfully prepared by using
simple sol-gel method. The structural property of as-prepared nanocrystalline materials was investigated by
using X-ray powder diffraction, Raman spectroscopy, Fourier transform infrared spectroscopy and scanning
electron microscopy. The infrared spectra of the prepared samples showed an incorporation of B and Ag in the
SnO2 nanocrystals. The X-ray powder diffraction pattern of the as prepared sample demonstrated the formation
of a rutile structure of SnO2 nanocrystallites with particle size of 35 nm and 98 nm for boron doped and co-doped
samples respectively. The two different Sn-O bond distances are found to be varying in a different manner for the
doped samples unlike pristine samples. A significant lattice microstrain was observed for co-doped samples
indicating local lattice distortion. The prepared samples showed significant anti-microbial activities against some
Gram-Positive & Gram-Negative
