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 (FESEM)
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.
