Paper Abstract

In this work, thermal and spectroscopic properties of antimony-germanate glasses have been presented. Investigated glasses with the different molar content of alkalis (Na2O and K2O) have been co-doped with erbium and silver ions in order to obtain luminescence in the near-infrared region. Along with the increment of alkalis content, an increase of thermal stability parameter ΔT has been observed. High concentration of Na2O and K2O in the glassy matrix results in the presence of a plasmonic peak at the wavelength of 454 nm originating from large volume fraction of silver nanoparticles. Change of the luminescence parameters in the near-infrared region (Er3+: 4 I13/24I15/2) has been observed in the function of alkalis content in the glass matrix, which high concentration increases the volume fraction and size of silver nanoparticles promoting the energy transfer channel Er3+→Ag.
