Ionic Self-Assembled Multilayers in a Long Period Grating Sensor for Bacteria and as a Source of Second-Harmonic Generation Plasmonically Enhanced by Silver Nanoprisms
… used to increase SHG. Colloidally grown silver nanoprisms were deposited onto nonlinear ISAM films and conversion of 1064 nm Nd:YAG radiation to its 532 nm second-harmonic was observed. Little enhancement was observed when using nanoprisms with LSP resonance near 1064 nm due to their large size …

Amorphous silica-based carbon nanotube and silver nanoprism coatings: synthesis and investigation of their optical properties /
In this thesis two type silica composite coatings were investigated which includes (i) silica-single-walled carbon nanotube (SWCNT) and (ii) silica-silver nanoprism (AgNPR) coatings. Research results showed, that the highest colloidal stability of SWCNTs in ethanol is obtained with surfactant P4VP. …
