Abstract:
The CdO:Fe nanopowder semiconductors were
synthesized by the sol–gel calcination for the first time.
The structural properties of Fe doped CdO samples were
analyzed by AFM and XRD measurements. XRD patterns
of the pure and Fe-doped CdO samples reveal that the pure
and Fe doped CdO nanopowders are polycrystalline of cubic
CdO structure. The crystallite size of undoped and Fe-doped
CdO samples is changed unsystematically with a regular
increase of Fe content. The optical band gaps of Fe doped
CdO samples were determined for the first time by diffused
reflectance measurements. The optical band gap of the samples is increased with the increase of Fe dopant inside the
host matrix (CdO) up to 15 % followed by a decrease in its
value. It is evaluated that Fe doped CdO nanopowder semiconductors can be producted by sol–gel calcination for
advanced technological applications
