AbstractABSTRACT Nanocomposite optical glasses and fibers give a novel way to manage luminescent properties of lanthanides ions, mainly due to their unique properties, obtained as a result of the interaction of metallic nanoparticles with photons. The most advanced systems are found in the currently used waveguide structures, characterized by sophisticated optical properties and an excellent thermal stability parameter required in modern optical fiber technology. State-of-art is a combination of noble metals properties, i.e. silver (Ag+), gold (Au+) and technology of rare earth (RE) ions doped glassy materials. Modification of emission properties of glassy materials doped with lanthanide ions, which is obtained by co-doping with nano-sized metal particles, is an innovative research area. One of the reasons of introducing nanoparticles of noble metal to glassy materials is the possibility of increasing the luminescence signal in the visible range by energy transfer between metal nanoparticles and rare earth elements and by enhancement of electric field within rare earth ions that results from the surface plasmon resonance. Studies concerning interaction mechanisms of noble metal nanoparticles on luminescent properties of active glasses are currently the subject of research being carried out by many scientific centers around the world. This will lead to new possibilities in the production of optoelectronic devices, including optical fibers sensors and sources currently being used in medicine, optics and nanophotonics (SERS – Surface-Enhanced Raman Scattering, LSPR – Local Surface Plasmon Resonance sensors). In this paper, an effect of silver and gold ions on luminescent properties of europium ions in antimony-germanate-borate SGB glass fibers is presented. The glass was synthesized by standard melt-quenching technique and glass fiber was drown at the temperature of 580°C. In the experiment, the interaction mechanism was investigated in terms of localized SPR in each step of the glass fiber fabrication process. Moreover, we demonstrate that self-assembling of silver nanoparticles on glass fiber surface exist only for fiber co-doped with AgNO3 ions. The non-conventional bottom-up technique of thin film of Ag nanoparticles was analysed by SEM measurements.
