    Raman spectroscopy and effective dielectric function in PLZT x/40/60

  • Original language description

    The Raman spectra of the ceramics PLZT x/40/60 have been measured in the temperature range 20?800 K. An assignment of the Raman modes is presented using the results of the effective medium approximation for the IR data. Factor-group analysis is presentedfor the case of off-site position of cations or unit cell doubling, which allows a higher number of active phonons in the IR and Raman spectra. The presence of Raman-active modes in the cubic phase is associated with local unit cell doubling and symmetry breakdown due to the off-site cations.

    Ramanová spektroskopie a efektivní dielectrická funkce v PLZT x/40/60

  • Czech description

    Ramanova spektra v keramice PLZT x/40/60 byla měřena v teplotním oboru 20-800 K. Určení Ramanovských módů je prezentováno pomocí aproximace efektivního prostředí pro infračervené módy. Grupová analýza je prezentována v případě off-site pozice kationtů čizdvojení buňky. Ramanovské aktívkní mody ve kubické fázi jsou spojené s lokalní zdvojení bunky a přerušení symetrii kvuli off-site kationů.
