Resumo
Measurements of the electric quadrupole interaction were used to characterize pure and cobalt-doped samples of SnO2 prepared by the sol-gel method.
Perturbed gamma–gamma angular correlation (PAC) spectroscopy using 111In–111Cd
probe nuclei was employed for these measurements. A methodology was developed
for sample preparation that were prepared by sol-gel method from pure metallic Sn
(99.9999%) and Co (99.9998%) as starting materials. Carrier-free 111In was added to
the precursor sol-gel solution prior to the formation of gel. PAC measurements were
carried out to follow the formation of the SnO2. PAC measurements were carried out
in the temperature range from 10 k to 1123 K and the results show that the electric
quadrupole frequency depends on the annealing temperature.
