Copper chloride (CuCl) and silver chloride (AgCl) nanoclusters are successfully formed by sequential implantation. Chlorine ions were firstly implanted into Al2O3 substrates to doses of the order 1017/cm2, and copper or silver ions were implanted subsequently. The energies of Cl+ (140 keV), Cu+ (240 keV) and Ag+ (360 keV) ions were chosen to produce overlapping concentration profiles in the matrix. It was found that CuCl and AgCl crystallites with 7-35 nm in diameter were formed without any thermal treatments subsequent to ion implantation. The optical absorption measurement reveals confinement of excitons in the CuCl nanoclusters.
