Tuning of the stop-band position in the visible range of SiO2/TiO2 Bragg reflectors by doping TiO2 with transition metals

Tuning of the stop-band position in the visible range of SiO2/TiO2 Bragg reflectors by doping TiO2 with transition metals

Within this paper, the influence of the doped-TiO2 layer with Cu, Ni, Co and Cr on the stop-band position of SiO2/TiO2 Bragg reflectors was investigated. The films crystallize into pure anatase phase whatever is the element of doping. As the atomic radius of the elements of doping raises (rCu
