Fluorescent glass embedded silver nanoclusters: An optical study

Abstract

In this report, the light emitting behavior of silver nanoclusters embedded in sodalime glass through ion-exchange technique is studied. The cluster sizes were varied through thermal annealing. The optical absorption spectra were recorded for all the glasses. The variation of surface plasmon resonance peak with the annealing temperature was found. Fourier transform infrared spectral measurement was utilized to identify the chemical interface damping. Photoluminescence measurements were carried out and time resolved photoluminescence was performed to identify the time evolution of emission.
