采用两步烧结法制备了（Pb，La）（Mg 1/3 Nb 2/3）O3-PbTiO 3（PLMNT）透明陶瓷。通过改变冷却速率，在相同成分的PLMNT透明陶瓷中形成了两种不同的畴结构。在快速冷却的样品中形成大的条状畴结构，而在缓慢冷却的样品中形成精细的指纹状畴结构。透明PLMNT陶瓷中的大畴结构引起光散射，降低了透射率。对于具有大畴结构的PLMNT陶瓷，截止波长也发生了红移，这归因于陶瓷中的内应力。不同畴结构的PLMNT陶瓷表现出不同的电学性能：与大畴结构的PLMNT陶瓷相比，细畴结构的PLMNT陶瓷具有较小的矫顽场、较大的电场诱导应变和较低的凝固温度（TVF）。
Transparent (Pb,La)(Mg1/3Nb2/3)O3–PbTiO3(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 (TVF).
