Title: Optical properties of SnO{sub 2} nanoparticles

SnO{sub 2} nanoparticles were successfully prepared by a sol-gel technique. The samples were analyzed by XRD, SEM, TEM, UV, Photoluminescence (PL) and Raman studies. The obtained product has a particle size of 12 nm with absorption peak at 278 nm. The absorption peak shows a blue shift when compared to the bulk due to quantum confinement. The FTIR spectrum of the prepared SnO{sub 2} nanoparticles exhibits a broad absorption band between 3100 and 3400 cm{sup −1} as well as a narrower peak at 1600 cm{sup −1}. The PL spectrum shows two strong peaks at 420 and 484 nm and broad peak between 430 and 470 nm.
