摘要

The processes going on in silver-doped GeO2 films during air-heating were investigated by XPS, TEM, IR and UV-visible spectroscopy methods. Silver was shown to interact with the GeO2 matrix at 500-600degreesC to give silver germanate which was decomposed on further heating to form GeO2 and silver nanoparticles, 10-35nm in size. absorbing in the plasmon resonance region (lambda(max) = 415nm). The silver nanoparticles are located deep in the films and encapsulated by oxide particles. (C) 2004 Elsevier B.V. All rights reserved.
