Abstract

Nucleation of gold nanoclusters in TiO 2(110) single crystal using ion implantation and subsequent annealing were studied by Rutherford backscattering spectrometry /channeling (RBS/C), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Approximately 1000 Au 2+/nm 2 were implanted at room temperature in TiO 2(110) substrates. TEM and SEM measurements reveal that rounded nanoclusters were formed during the implantation. In contrast, subsequent annealing in air for 10 hours at 1275 K promoted the formation of faceted (rectangular shaped) Au nanostructures in TiO 2. RBS channeling measurements further reveled that Au atoms randomly occupied the host TiO 2 lattice during the implantation. However, it appears that some Au atoms moved to the Ti lattice positions after annealing.
