| Abstract |
A new class of glass-ceramic nanocomposite systems with a uniform distribution of SnO2 nanocrystals dispersed within an amorphous silica phase is fabricated in the form of thin films by using sol gel processing. In this work, experiments with (100-x)SiO2-xSnO(2) nanocomposite thin films with (x=25 and 30 mol\%) doped with Er3+ ions (concentrations of 0.5, 1 and 2 mol\%) are presented. The focus has been both to determine the effect of rare-earth doping on the growth of SnO2 nanocrystals as well as the distribution of the Er3+ ions within the ceramic structure. Vibrational spectroscopic assessments have proven the glass-ceramic nature of the samples. EXAFS and photoluminescence spectra show that the rare-earth ions exist in both amorphous and crystalline phases. Moreover an energy transfer from SnO2 nanocrystals to erbium ions on excitation at 351 nm is demonstrated. |
