Abstract
In this article, we present the effects of Ag doping and after-growth thermal annealing on the photoluminescence (PL) and thermoluminescence (TL) behaviors of <TEX>$SnO_2$</TEX> nanoparticles. <TEX>$SnO_2$</TEX> nanoparticles of 4-7 nm size range containing different Ag contents were synthesized by hydrothermal process. It has been observed that the after-growth thermal annealing process enhances the crystallite size and stabilizes the TL emissions of <TEX>$SnO_2$</TEX> nanostructures. Incorporated Ag probably occupies the interstitial sites of the <TEX>$SnO_2$</TEX> lattice, affecting drastically their emission behaviors on thermal annealing. Both the TL response and dose-linearity of the <TEX>$SnO_2$</TEX> nanoparticles improve on 1.0% Ag doping, and subsequent thermal annealing. However, a higher Ag content causes the formation of Ag clusters, reducing both the TL and PL responses of the nanoparticles.
