Germanate Glasses

In this paper, heavy metal oxide glasses co-doped with erbium and holmium ions have been synthesized. Glass composition, based on the bismuth and germanium oxides, has been selected in terms of high thermal stability (delta T = 125 °C), high refractive index (n = 2.19) and low maximum phonon energy (hvmax = 724 cm-1). Up-conversion luminescence spectra under the 980 nm laser diode excitation have been observed as a result of radiative transitions within the quantum energy level structures of Er3+ and Ho3+ ions. Optimization of rare earth ions content has been conducted, the highest emission intensity in the visible wavelength range has been observed in glass co-doped with molar concentration 0.5 Er2O3 / 0.5 Ho2O3.

The article presents the possible mechanisms of interaction between emission of Eu3+ ions and surface plasmon resonance (SPR) from Ag0 nanoparticles. The antimony-germanate glasses were synthetized by standard melt-quenching method. The influence of high-phonon glass forming compounds on excitation and luminescence spectra was analysed. Also, we showed that Sb2O3 is a mild reducing agent of noble metal ions. This mild reduction property enables thermochemical reduction of Ag+ to Ag0 in a single-step during the melting process. The energy transfer mechanisms between Eu3+ ions and Ag0 nanoparticles were also discussed in terms of local field effect of Ag0 nanoparticles. Full Text: PDF ReferencesS. Chatterjee, S. K.
