Abstract
In this work, (100-x)SiO2-xSnO2 (with x = 10, 20 and 30% mol) doped with 1mol% Er3+ nanocomposite thin films were prepared by sol-gel method. The effect of SnO2 concentration in the structure and the distribution of erbium ions in ceramic-glass structure were investigated by FT-IR spectroscopy, X-ray diffraction (XRD) and Atomic Force Microscopy (AFM). SnO2 nanoparticles with size about 50nm were formed in films heat-treated at 1000oC. Photoluminescence and 3D spectroscopies show that there is the energy transfer from SnO2 nanocrystal to erbium ions and the ions exist in amorphous environment and in the nanoparticles.
