摘要：
The sol gel technique was successfully used to synthesize the nanocrystals of tin dioxide (SnO2), co-doped with aluminium (Al) and yttrium (Y). The powders were preheated at different temperatures ranging from 200 to 1000 degrees C. The effects of temperature and dopants on the structure of tin dioxide nanoparticles were investigated. X-ray powder diffraction (XRD) and Raman spectroscopy were used to probe the structural properties. The average crystallite sizes were found to be in the range between 2.5 - 8 nm in the temperature range studied. Both techniques confirm that at higher temperatures there is a high temperature reaction resulting in the formation of yttrium stannate
