Abstract

A series of silver ( Ag 0 ) nanoclusters embedded in bismuthate glasses ( Bi 2 O 3 - B 2 O 3 - TiO 2 ) were synthesized by the thermochemical reduction method. When B 2 O 3 was substituted with TiO 2 , the refractive index of the encapsulating medium increased, leading to redshifting of the surface plasmon resonance (SPR) absorption band of Ag 0 , which was initially located at 612 nm . Z-scan measurements with femtosecond laser pulses at 800 nm showed that third-order optical nonlinearities (TONs) were significantly enhanced in the SPR redshifted samples, and calculation of the figure of merit manifested excellent performances of present Ag 0 -bismuthate nanocomposites for TON-based all-optical switching.
