Nanocrystalline Al/Y co-doped tin oxide powders were successfully synthesized using the sol-gel method. The samples were subjected to different temperatures ranging from 200 to 1000 degrees celsius. The effects of co-doping and temperature on the structural properties of Al/Y co-doped tin oxide nanoparticles were investigated. The characterization techniques used were X-ray powder diffraction (XRD) and Raman spectroscopy. The average particle sizes were found to be in the range between 2.5 – 8 nm in the temperature range studied while the strains were in the range between 2.76 – 0.53. Both the XRD and Raman spectroscopy confirm that at higher temperatures yttrium stannate is formed.
