Optical and structural characterization of SrZr0,1Ti0,9O3

► The ceramic nano structured compound SrTi0.90Zr0,1O3 was synthesized by the citrate method. ► Differential and gravimetric thermal analysis showed the right thermodynamical parameters ► Good agreement between the crystal structure, group theory and the optical properties was obtained. ► The sized and high crystallinity of the nanoparticules was confirmed by SEM and TEM. ► Crystal structure is tetragonal with space group I4/mcm was found by X-ray and Rietveld refinement.
