“…For plasmonic applications the dimension of nanoclusters is crucial. The average sizes of the nanoclusters estimated from the TEM images were found to be 2.9 nm, 4.4 nm and 7.2 nm for samples annealed at 500 1C, 550 1C and 600 1C, respectively, for 1 h (as shown in the histogram plots) which are in good agreement with the cluster sizes (shown in Table 1) calculated by eqn (1). Analysis of the high resolution TEM images of the samples annealed at 550 1C and 600 1C show that the spherical particles consisted of a crystal lattice with d-spacing of 0.24 nm, which corresponds to the (111) plane of Ag nanoclusters.…”

“…This fact is largely due to their advantage in manipulating light at the nanoscale by exploiting the interaction of light with metallic nanostructures, which exhibit interesting surface plasmon resonance (SPR) phenomena. 1,2 The plasmonic behaviors of metallic nanostructures have drawn enormous scientific interest due to their unique and unusual physicochemical properties and functionalities compared to their bulk counterparts. These properties make them attractive in various applications such as plasmonics, 3,4 nanoelectronics, 5,6 biotechnology 7,8 and nanophotonics.…”

Silver nanoclusters were prepared in a soda-lime glass matrix through the ion-exchange (Ag(+)↔ Na(+)) method followed by thermal annealing in an air atmosphere. The nanoscale patterning of Ag nanoclusters embedded in a soda lime glass matrix in an air atmosphere at different annealing temperatures has been investigated. During annealing, Ag(+) is reduced to Ag(0) and subsequently forms silver nanoparticles inside the glass matrix. A blue shift of 20 nm has been observed as a function of the post annealing temperature. The photoluminescence intensity is highest for an annealing temperature of 500 °C for 1 h and continuously decreases as annealing temperature increases up to 600 °C. The presence of spherical nanoparticles with a maximum particle size of 7.2 nm has been observed after annealing at 600 °C for 1 hour, which is consistent with Mie theory based results.
