Structural and optical properties of La 2 NiTiO 6 double pervoskite

Abstract

Among multifunctional La 2 BB'O 6 (B/B' are transition metals) with d 6 -d 0 nature, double perovskites, La 2 NiTiO 6 has recently received significant attention due to its rich physics and prospects in technological applications. In the present study, La 2 NiTiO 6 (LNTO) was synthesized via citrate route. The profile analysis of room temperature X-ray diffraction data emphasized on the formation of single phase monoclinic (P21/n) LNTO ceramics. While, in order to optimize the type of band-to-band transition in the synthesized sample, the optical absorbance spectra recorded in the wave length range (200-1100) nm.
