| dc.description | The Raman spectra in the nanocrystalline Pb<sub>1-x</sub>Sr<sub>x</sub>TiO<sub>3</sub> system show that the morphotropic phase transition from the tetragonal phase to the cubic structure occurs at x<sub>c</sub>=0.57 and it can be associated with 'softening' of the lowest-frequency E(TO) phonon mode. The phase transition temperature in Pb<sub>0.8</sub>Sr<sub>0.2</sub>TiO<sub>3</sub> decreases with decreasing grain size. The disappearance of the ferroelectric phase of Pb<sub>0.8</sub>Sr<sub>0.2</sub>TiO<sub>3</sub> has been discussed as a function of grain size. The correlation between the temperature-induced and the Sr-concentration-induced phase transition in nanocrystalline Pb<sub>1-x</sub>Sr<sub>x</sub>TiO<sub>3</sub> has been observed. |
