Abstract :
Strontium titanate (SrTiO3) is useful in many technological applications and it´s properties are strongly dependent on the doping of it´s A or B site. We have performed temperature dependent Raman studies of SrTi0.9M0.1O3 (M = transition metal) nanoparticles. Our results indicate that the mode energies and symmetry of the SrTiO3 structure have been changed as doped with various transition metals, such as Fe, Co or Ni. However, these changes depend on the type of the doping element and the doping content.
