“…Relatively large n 2 of glasses indicates the utility in ultrafast all-optical switching applications. [26,86,87] Among the glasses considered in the present study, the Au-50-15 glass exhibits high I S and n 2 values. The highest I S and n 2 characteristics attained for Au-50-15 glass are compared with many advanced materials a commercially available ones by tabulating the values in Table 2.…”

“…The obtained I S values for the Au‐50‐15 glass are significantly greater than GNPs dispersed in sodium carboxy methylcellulose [ 85 ] and higher than currently utilizing NLO materials such as organic dyes (first materials to be used as SAs), [ 97 ] color‐filter glasses, [ 98 ] and dye‐doped solids. [ 99 ] Further, the maximum n 2 obtained for Au‐50‐15 glass is one and two orders greater than tellurite [ 86 ] and fused silica glasses, [ 26 ] respectively. The n 2 values are higher than the commercially using potassium dihydrogen phosphate crystals and lithium niobate crystals.…”

“…Glass materials, known for their environmental friendliness, have been incorporated into a wide range of applications across the biological, optical, photonic, and energy sectors. [23][24][25][26][27] This versatility stems from their flexible thermal, optical, mechanical, and electrical properties, which can be precisely adjusted by altering their chemical composition. Glass substrates offer a number of benefits, including a smooth, transparent surface, simple handling, robustness, cost-effective, and chemical inertness.…”

Metal nanoparticles (MNPs) are synthesized using various techniques on diverse substrates that significantly impact their properties. However, among the substrate materials investigated, the major challenge is the stability of MNPs due to their poor adhesion to the substrate. Herein, it is demonstrated how a newly developed H‐glass can concurrently stabilize plasmonic gold nanoislands (GNIs) and offer multifunctional applications. The GNIs on the H‐glass are synthesized using a simple yet, robust thermal dewetting process. The H‐glass embedded with GNIs demonstrates versatility in its applications, such as i) acting as a room temperature chemiresistive gas sensor (70% response for NO2 gas); ii) serving as substrates for surface‐enhanced Raman spectroscopy for the identifications of Nile blue (dye) and picric acid (explosive) analytes down to nanomolar concentrations with enhancement factors of 4.8 × 106 and 6.1 × 105, respectively; and iii) functioning as a nonlinear optical saturable absorber with a saturation intensity of 18.36 × 1015 W m−2 at 600 nm, and the performance characteristics are on par with those of materials reported in the existing literature. This work establishes a facile strategy to develop advanced materials by depositing metal nanoislands on glass for various functional applications.
