The blueviolet photoluminescence (PL) response of ion beam synthesized Sn nanoparticles (NPs) in silica is studied in samples submitted to a two-step thermal annealing process. This process consists of a low temperature and long time ageing treatment (523K, 100h) followed by a high temperature and short time one (T>773K, 0.5h). The comparison between aged and non-aged control samples by means of transmission electron microscopy observations and Rutherford backscattering spectrometry...[Show more]
