Figure 8From: Influence of transition metal doping on the structural, optical, and magnetic properties of TiO2 films deposited on Si substrates by a sol–gel processImaginary part ϵ i and real part ϵ r of the complex dielectric functions of the undoped and TM-doped TiO 2 films. For clarity, the ϵi and part ϵr of the films are shifted by 2 and 5, respectively.Back to article page
