	%X In the present study, we have synthesized Cr and Fe
doped zinc oxide (ZnO) nanostructures (Zn1-&delta;CraFebO; where &delta; = a +
b = 20%, a = 5, 6, 8 &amp; 10% and b = 15, 14, 12 &amp; 10%) via sol-gel
method at different doping concentrations. The synthesized samples
were characterized for structural properties by X-ray diffractrometer
and field emission scanning electron microscope and the optical
properties were carried out through photoluminescence and UVvisible
spectroscopy. The particle size calculated through field
emission scanning electron microscope varies from 41 to 96 nm for
the samples synthesized at different doping concentrations. The
optical band gaps calculated through UV-visible spectroscopy are
found to be decreasing from 3.27 to 3.02 eV as the doping
concentration of Cr increases and Fe decreases.
