Abstract
Tin dioxide (SnO 2 ) nanoparticles having 3 nm size were synthesized by irradiating pure tin metal using high power Nd:YAG laser in deionized water. Formation of nano-SnO 2 crystallites was confirmed by X-ray diffraction (XRD) and AFM study. UV-vis absorption spectral studies showed a peak at 240 nm. FTIR spectrum showed a band in the range of 400-700 cm -1 which was assigned to Sn-O antisymmetric vibrations. Photoluminescence spectrum of synthesized SnO 2 nanoparticles showed peak corresponding to 3.175, 2.901 and 2.613 eV respectively.
