“…One can reduce this loss effectively by selecting the appropriate glass composition that has a low melting temperature [23]. For instance, in the present study, Borate has been selected as a part of the glass composition due to its glass-forming ability [24] whereas Bismuth acts as a glass modifier that reduces the melting temperature of glass and hence obstructs the loss of AuNPs. In addition, the use of refractory material as one of the components of glass composition can protect the AuNPs from high temperature steps.…”

In the present work, a new approach is introduced to mitigate the loss of gold nanoparticles while preparing the glass through the traditional melt-quench technique. The role of refractory material i.e. SiO¬2 in loss reduction is studied by comparing the results obtained for bismuth borate (40Bi2O3:60B2O3) and borosilicate (40Bi2O3:40B2O3:20SiO2) glasses containing gold nanoparticles of different sizes (10 nm, 40 nm and 100 nm). The particle density and thermal stability obtained from FESEM and DTA, respectively, increase considerably with the presence of SiO2 as one of the components of glass composition. The nonlinear optical behaviour of both systems in non-resonant regions has been obtained using the Z-scan technique. In addition, the suitability of the prepared glasses for optical limiting and switching applications has been analysed.

“…25,26 One of the most interesting ones is the enhancement of NLO properties by noble metals' surface plasmon resonance (SPR) phenomenon. [27][28][29][30] Due to its advantageous combination of high carrier concentration and low cost, Ag has emerged as the preferred material for metal-semiconductor composite structures. Furthermore, the TCO/metal/TCO structure, which has been extensively investigated, is designed to simultaneously achieve high electrical conductivity and transmittance in the visible range.…”

Ultrafast nonlinear absorption properties of SnO2/Ag/SnO2 composite films based on Z-scan measurement

To explore the nonlinear absorption (NLA) properties of the SnO 2 composite system, SnO 2 ∕Ag∕SnO 2 (SAS) composited films were prepared by magnetron sputtering at room temperature. The NLA properties were investigated using femtosecond Zscan technology at a wavelength of 800 nm. The results show that as the sputtering power of the Ag layer increases, the NLA type of the composite films changes from reverse saturated absorption to saturated absorption. According to the research results, adding the Ag layer can regulate the NLA type of composite films. In addition, by increasing the sputtering power of the Ag layer and the incident laser energy intensity, the NLA behavior of the composite films is improved. Compared with the monolayer SnO 2 film, the NLA coefficient (β) of the composite film has increased by 17 times. We provide a new perspective for the application of SAS composite films in optoelectronic devices.
