Enhancement of D(sub o)(super 5)-F(sub J)(super 7) emissions of Eu3+ ions in the vicinity of Polymer-protected Au nanoparticles in sol-gel derived B2O3-SiO2 glass
Article Abstract:
A nanometer-sized gold (Au) colloids, synthesized in solution is incorporated into a borosilicate (B2O3-SiO2) glass matrix together with Eu3+ ions via a sol-gel route to investigate the enhanced photoluminescence of trivalent europium (Eu3+) ions in the vicinity of nanometer-sized metal particles in glasses. Results revealed an enhanced fluorescence of D(sub o)(super 5)-F(sub J)(super 7) transitions of Eu3+ in the vicinity of gold nanoparticles due to high order of surface plasmon resonance (SPR) excitations.

Optical properties and valence change of europium ions in a sol-gel Al2O3-B2O3-SiO2 glass by femtosecond laser pulses
Article Abstract:
The optical properties and valance change of the Eu(super 3+) ions in the Al2O3-B2O3-SiO2 glass are investigated. The analysis of the fluorescence line-narrowing spectra (FLN) spectra indicates that there are two kinds of surroundings of the Eu(super 3+) ions.
