Gripe water-mediated green synthesis of silver nanoparticles and their applications in nonlinear optics and surface-enhanced Raman spectroscopy

Abstract

In the present study, silver nanoparticles were synthesized from aqueous silver nitrate through a simple, eco-friendly and 'green' method using gripe water as reducing as well as stabilizing agent. Control over the dispersity of silver (Ag) nanoparticles was attained by altering the synthesis process. The size and morphology of the particles were perceived using high-resolution transmission electron microscope and the surface plasmon resonance of the prepared nanoparticles was observed by UV-VIS spectrum. Herein, we report the nonlinear optical behavior and surface-enhanced Raman spectroscopy of silver nanoparticles with different particle size and dispersity. The nonlinear optical behavior was studied by single beam Z-scan technique using tunable Ti: Sapphire mode-locked femtosecond laser as source. The nonlinear optical parameters such as the nonlinear refractive index, nonlinear absorption coefficient b and the third-order nonlinear susceptibility v 3 of the prepared Ag nanoparticles were obtained for various wavelengths by tuning the wavelength of the laser from 700 to 950 nm. Surfaceenhanced Raman spectroscopy (SERS) is an inspiring phenomenon especially in the case of silver nanoparticles. The as-synthesized silver nanoparticles show huge enhancements in the order of 10 9 in the Raman spectrum of rhodamine 6G dye.

“…4a, 4b. The synthesised Ag nanoparticle size varies with the amount of reducing agent adding to the source materials [28]. The synthesised Ag nanoparticles were nearly quasi-spherical in shape in poly dispersed manner and size varies from 5 nm to 15 nm.…”

Thermosensitive Behavior and Super-Antibacterial Properties of Cotton Fabrics Modified with a Sercin-NIPAAm-AgNPs Interpenetrating Polymer Network Hydrogel

“…Presently, green chemistry has become an important topic. The key to the preparation of metal nanoparticles lies in the selection of environmentally friendly reducing agents and non-toxic nanoparticles [12,13]. Raveendran et al used soluble starch as a template and β- d -glucose as a reducing agent to synthesize AgNPs in water [14].…”

Extracellular Biofabrication of Silver and Gold Nanoparticles: Treasures From the Abyssal Zone

“…In this review, we have depicted that though there are different ways of compounding MNPs, only biological methods can satiate the need for a facile, green, nontoxic, sustainable, and highly efficient method. Of late, several resources such as plants, microorganisms, Ayurvedic formulations such as arishtams [88], kashayam [89], gripe water [90], honey [91,92], amino acids [93], isolated phytoconstituents like crocin [94], and carbohydrates like dextrin [95] have been explored in MNPs synthesis. Thus, researchers have now focused their attention toward marine sources, a hub of active molecules, which are underutilized in this particular field.…”
