Abstract

We report the plant-mediated synthesis, structural investigation, optical properties and theoretical modelling of atriclinic (anorthic) phase AgCoPO4nanoparticles for thefirst time. As part of green chemistry, the secondarymetabolites in the leaf extract ofCanna indicawere engaged as the reducing/capping agent for the metal nano-particles. X-ray diffraction (XRD) revealed the presence of an anorthic AgCoPO4phase, crystallised in a triclinicstructure with P -1 space group. Optical studies using UV-vis spectroscopy and photoluminescence are reported.Transmission electron microscopy suggests the formation of quasi-nanocube morphology, unlike the conventionalspherically-shaped nanoparticles via plant-mediated reduction method. Elemental composition of the nanohybridwas confirmed by energy-dispersive x-ray spectroscopy (E.D.S.). Evidence of crystallinity was supported byselected area electron diffraction (SAED). Study of the dynamic anisotropy of the nanohybrid at optimised statesuggests its proposed application as optical material in colourimetric metal nanoparticles-mediated sensors.
