摘要：

In this article, we report the photoluminescence of three different systems produced by ion implantation: a high-purity silica substrate with silicon nanocrystals and two samples containing silicon nanocrystals in the vicinity of silver nanoparticles. The silicon nanocrystals were formed inside silica matrix by 1.5MeV implantation of silicon ions and annealing. Subsequent implantations with silver ions at different energies were performed to vary the distance between the previously formed silicon nanocrystals and newly aggregated silver nanoparticles. The samples were studied by photoluminescence, Rutherford backscattering spectrometry, m-line, and optical absorption. The enhancement of photoluminescence is well evidenced at the lowest implantation energy of silver, but at higher energies, a decrease in intensity is observed.
