Abstract EN
Co and Cd have been codoped in ZnO using a simple solid state reaction technique to synthesize dilute magnetic oxide semiconductors of composition Zn0.9Co0.1−xCdxO (x = 0.0-0.1 with an increment of 0.02).
Hexagonal wurtzite structure has been obtained for samples up to x = 0.06, using X-ray diffractometry.
However, at x = 0.08 and 0.1, secondary peak of CdO is observed.
Raman spectra of the samples have been obtained in 200–800 cm−1 range.
UV-VIS spectrophotometer is used to study the optical properties, which shows that band gap energy decreases with the increase in Cd concentration.
A weak ferromagnetic behavior was evident which decreased further by adding Cd in the series.
Room temperature resistivity measurements performed using four-point probe technique showed that their values lie in the semiconductor range.
Structural morphology of the samples has been investigated by a scanning electron microscope and grain size has been determined.
Raman spectra and Fourier transform infrared spectroscopy revealed the successful incorporation of Co and Cd ions into the host ZnO lattice.
