SYNTHESIS AND CHARACTERISATION OF ZnO AND SIVER DOPED ZnO NANOPARTICLES
Keywords:
ZnO nano particles, co-precipitation, antibacterial, photoluminescenceAbstract
ZnO Nano materials have attracted a wide attention of researchers due to their excellent properties and immense
applications in many fields. In the present work pure ZnO and Ag doped ZnO nano particles with capping agent were
synthesized by co-precipitation method. The prepared samples were characterized for their Structural, Morphological,
Antibacterial and Photoluminescence properties. The average Grain size of ZnO, Ag doped ZnO was determined and was
found to increase in the case of Ag doped ZnO samples when compared with undoped ZnO samples. The SEM image of Ag
doped ZnO shows tube like structure. Ag doped ZnO shows inhibitory effect on the growth of E.Coli. PL spectra of the
samples indicate the presence of narrow emission band in the uv region centered around 385 nm.
