Annealing effects on the structural and dielectric properties of (Nb + In) co-doped rutile TiO ceramics.

Density functional theory calculations were conducted to investigate the electronic structures of rutile TiO, TiNbInO, and TiNbInO systems. High density (Nb + In) co-doped rutile TiO ceramics were successfully prepared by one modified solid state method. XRD, XPS, Raman scattering and FT-IR measurements were performed to investigate the structural properties of the (Nb + In) co-doped rutile TiO ceramics annealed in different atmospheres.
