Formation and control of Au and Ag nanoparticles inside borate glasses using femtosecond laser and heat treatment

Surface Plasmon Resonance and Enhanced Fluorescence Application of Single-step Synthesized Elliptical Nano Gold-embedded Antimony Glass Dichroic Nanocomposites

“…Realization of the above phenomena in active and real functional devices with plasmonic nanoparticles requires a fundamental control of their synthesis/insertion within solid-state environment. Consequently metal-dielectric (here glass) composites are receiving significant exposures [9][10][11][12][13][14][15][16][17][18][19][20]. Such metal-dielectric (glass) nanocomposites also find other ubiquitous applications like solid-state lasers, sensors, memory devices, dichroic polarizers, colored glasses, ophthalmic lenses, display devices, and opto-electronic materials due to non-linear optical properties [9][10][11][12][13][14][15][16][17][18][19][20].…”

“…Preparation of nano metal-doped conventional glass systems are not simple and demand multi-step techniques like sol-gel process, metal-dielectric co-sputtering deposition, direct metal-ion implantation, pulsed laser deposition, ion-exchange of thin plates, followed by long time heat treatment at high temperatures in reducing (hydrogen) atmosphere or UV-light/X-ray/ 60 Co γ-radiation or laser/ synchrotron irradiation [9][10][11][12][13][14][15][16][17][18][19]. These customary techniques are generally used to incorporate thin layers of spherical or quasi-spherical metal nanoclusters within high phonon (resonance vibration energy of the matrix) matrices like silicate, borate, and phosphate glasses.…”

Generation of copper nanoparticles induced by fs-laser irradiation in borosilicate glass

“…Recently, several studies on the production of metallic nanoparticles in glass by femtosecond laser excitation have been carried out [12][13][14]. Most of the papers, however, have been focused on gold and silver nanoparticles, and little attention has been given to copper, which has been shown to present high optical nonlinearities [2].…”

The effect of Au/Ag ratios on surface composition and optical properties of co-sputtered alloy nanoparticles in Au–Ag:SiO2 thin films

“…Recently, much effort has been devoted to the fabrications of nanocomposite metals, including alloy [5][6][7], core-shell [8] and mixed particles [9,10], because of their valuable properties for applications in nonlinear optics [11], catalysis [12], as well as surface enhanced Raman scattering [13].…”
