摘要：

The implantation of transition metal ions in glasses can lead to the formation of nanometer-sized colloidal particles embedded in a thin surface layer. In the present work, silica glasses implanted with Cr+ at energy E = 200 keV, for fluences larger than 10(17) ions/cm(2) were studied by electron paramagnetic resonance, X-ray photoelectron and X-ray-excited Auger electron spectroscopies, visible optical spectroscopy and scanning transmission electron microscopy (TEM). It is shown that Cr is present in silica glass as isolated Cr3+ ions as well as chromium oxides (antiferromagnetic Cr2O3 and ferromagnetic CrO2) and chromium silicides. TEM indicates the presence of almost spherical colloidal particles about 10 nm in diameter. (C) 2002 Elsevier Science B.V. All rights reserved.
