Study of Raman Spectra of Pb 3 (P 0.5 V 0.5 O 4 ) 2 Crystallized in Nanoscale Opal Pores

The results of Raman spectra investigation of dielectric Pb 3 (P 0.5 V 0.5 O 4 ) 2 crystallized in pores of synthetic opal are presented. The comparative analysis of these spectra with Raman spectra of Pb 3 (P 0.5 V 0.5 O 4 ) 2 in the monocrystalline state is carried out. Due to fitting o the spectra it was possible to reveal the changes in position of the spectral lines and their half-widths. It was shown that these effects may be caused by changing in the lengths of bonds inside the Pb 3 (P 0.5 V 0.5 O 4 ) 2 molecule as a result of crystallization in nano-sized pores of synthetic opal.
