Silver doped sodium borate glass was made by the melt quenching technique. As made glass, did not
reveal any absorption transitions in the visible or ultraviolet region. Differential scanning calorimeter was used to
measure glass transition temperature. Heat treated glass revealed absorption peak at 410 nm due to surface plasmon
resonance. Under violet laser excitation the glass revealed emission at 450 - 620 nm, whose lifetimes are more than
30μs. Under near resonant excitation it revealed intense Raman scattering. We also made multielement oxide
glasses co-doped with silver and Er3+ and performed spectroscopic studies. Energy upconversion was observed
from Er3+ at 415 nm in a 2% Ag co-doped oxide glass but not in other glasses. Infrared to visible upconversion
studies were performed in all these glasses under near-infrared laser excitation. 2% Ag doped glass exhibited
enhanced upconversion signals from erbium than that of other glasses.
