TL;DR: Theoretical data using ab initio perturbed ion calculation were compared with ferroelectric and piezoelectric experimental data of strontium doped PZT.

TL;DR: The phase formation mechanism of lead zirconate titanate (PZT) processed by a partial oxalate method was investigated by simultaneous thermal analysis (TG-DTA) and by qualitative and quantitative X-ray diffraction (XRD).

TL;DR: In this paper, the polymeric precursor method was used to obtain reactive Zr x Ti 1 − x O 4 (x = 0.65, 0.50 and 0.35) powder.

TL;DR: In this paper, a solution of oxalic acid was prepared with particles of ZT, Pb(NO3)2 and La2O3 followed by calcined and X-ray diffraction (XRD) showed the cubic phase of PLZT This material was sintered, in two steps, and a density of about 80 g/cm3 was obtained After the second sintering the XRD pattern showed the occurrence of tetragonal and rhombohedral phases This was caused by a stoichiometric deviation and the material showed a high optical transparency

TL;DR: In this paper, the photoluminescence at room temperature was observed in amorphous zirconium titanate obtained from the polymeric precursor method, which was the first time in which PL was noticed in a compound made of two network formers and was deconvoluted into two bands, whose center 1 was located from 540 nm to 552 nm and center 2 from 625 nm to 641 nm.
