Abstract
Knowing the morphology of Copper nanoparticles was confirmed by Field Emission
Scanning Electron microscopy (FE-SEM). Herein, we are reporting a novel biological approach for the
formation of copper nanoparticles using leave. Copper sulphate was made to reduce with aqueous
solution of Cassia auriculata leave extracts. X-Ray diffraction (XRD) pattern reveals the formation of
Copper nanoparticles, which shows crystallinity. Field emission scanning electron microscopy (FE
SEM) suggested particles size and spherical shape in the range of 38.1-43.5 nm. UV absorption studies
of copper naoparticles showed that have absorbance in the range 488.5 to 514.3 nm and FT-IR studies
of copper nanoparticles were showed that the stretching frequency of finger print region at 509.21 cm-1
for Cu-O bond.
