'a biosynthesis method for large area preparation of silver thin film containing nanoparticles'

摘要

The present investigation is related to the biosynthesis method for preparation of nanocrystalline and compact silver thin films onto glass substrates. Silver thin films containing nanoparticles have been deposited onto the large area glass substrates from the acidic bath at different temperatures using solution of AgNO3 and guava leaves extract. As confirmed from X-ray diffraction (XRD) pattern and scanning electron microscopy (SEM) images, silver thin films with nanoparticles have been deposited with unequal sized circular grain morphology. The absorbance peak of the sample at λ max, 450 nm, is associated with the characteristics peak of silver nanoparticles. The maximum value of transmission is around 80 %.
