Abstract: At room temperature band-gap in SnO2 Nanoclusters for an average diameter 6 and 10nm are determined. The values of band-gap are 3.543 and 3.351eV, respectively. The results are compared with the calculated values from the effective-mass approximation model.

Key words: SnO2 nanoclusters, band-gap
