The influence of domain structure on the optical and electrical properties of transparent (Pb,La)(Mg1/3Nb2/3)O3–PbTiO3 ceramics
Source abstract
Abstract
Abstract Transparent (Pb,La)(Mg 1/3 Nb 2/3 )O 3 –PbTiO 3 (PLMNT) ceramics were prepared by two stage sintering method. Two different domain structures were formed in PLMNT transparent ceramics with the same composition by changing the cooling rate. Large strip-like domain structure was formed in rapidly-cooled samples, while fine fingerprint-type domain structure was formed in slowly-cooled samples. The large domain structure in transparent PLMNT ceramics caused light scattering and decreased the transmittance. The cut-off wavelength was also red-shifted for PLMNT ceramics with large domain structure, which was attributed to the inner stress in the ceramics. PLMNT ceramics with different domain structures showed different electrical properties: Compared with PLMNT ceramics with large domain structure, PLMNT ceramics with fine domain structure had smaller coercive field, larger electric field induced strain and lower freezing temperature ( T VF ).
