a- and b-axis-oriented Bi3.25Nd0.75Ti3O12 (BNT-0.75) and Bi3.25Nd0.75-xEuxTi3O12 (BNEuT, x = 0-0.75) films of 3.0 um thickness were fabricated on conductive Nb:TiO2(101) substrates containing 0-0.79 mass% Nb by high-temperature sputtering. The optimal sputtering conditions (excess Bi2O3, deposition temperature, gas pressure and effective power density) to fabricate the ferroelectric nanoplates were investigated. By evaluating the physical properties of the resultant bismuth layer-structured ferroelectric nanoplates, it was demonstrated that the developed nanoplates had the potential as microelement materials for ferro- and piezoelectric, and multiferroic applications.

采用高温溅射法在Nb含量为0 ~ 0.79mass %的Nb：TiO_2（101）基片上制备了厚度为3.0 μ m的a轴和b轴取向的Bi_（3.25）Nd_（0.75）Ti_3 O_（12）（BNT-0.75）和Bi_（3.25）Nd_（0.75-x）Eu_xTi_3 O_（12）（BNEuT，x = 0 ~ 0.75）薄膜。研究了制备铁电纳米片的最佳溅射条件（过量Bi 2 O3、沉积温度、气压和有效功率密度）。通过评估所得铋层结构的铁电纳米片的物理性能，它被证明，开发的纳米片具有作为铁和压电，和多铁应用的微元件材料的潜力。
