Title: Surfactant free hydrothermal synthesis of SnO{sub 2} nanorods with their microstructure and Raman studies

SnO{sub 2} nanorods were prepared by hydrothermal method without any surfactant. Their microstructure was studied with X-ray diffraction, Raman scattering and transmission electron microscopy. The range of nanorods diameter size is ∼3 to 19 nm. The crystal structure was confirmed to be SnO{sub 2} rutile tetragonal structure. The nanorods were single crystalline in nature as confirmed by HRTEM. Electron energy loss studies were carried out. EELS analysis showed presence SnO{sub 2} phase and SnO phase was not observed. New Raman modes (352 and 579 cm{sup −1}) corresponding to small size effects were observed for the SnO{sub 2} nanorods.
