Abstract

The transparent relaxor ferroelectric ceramics of the system lanthanum modified lead magnesium niobate (PLMN-13PT) have been investigated for a variety of electro-optic, properties; good electro-optic switching times and modest half-wave voltages. In this work, the dependence of microstructural, structural, dielectrical, optical, and electro-optical properties in function of Rare Earth (RE = Tm³⁺, Nd³⁺, Yb³⁺, Er³⁺ and Ho³⁺) has been reported. PLMN-13PT:RE with excellent properties were obtained, highlighting the electrical, optical, and electrooptical properties, suitable for the fabrication of multifunctional devices. The most prominent or important feature is the largest quadratic Electro-optic coefficient achieved ((9.37 ± 0.39) × 10⁻¹⁶ m²/V²) corresponding to PLMN-13PT:Ho transparent ceramics. This result in addition to the electrical and photoluminescence properties becomes a promising alternative to building multifunctional devices.

稀土添加剂对PLMN-13PT:RE透明陶瓷性能的影响

研究了镧改性铌酸铅镁(PLMN-13PT)体系的透明弛豫铁电陶瓷的各种电光性能;良好的电光开关时间和适度的半波电压。本文报道了稀土(RE = Tm3+， Nd3+， Yb3+， Er3+和Ho3+)的微观结构，结构，介电，光学和电光性质在功能上的依赖关系。得到了性能优异的PLMN-13PT:RE，突出了电学、光学和电光性能，适合于制造多功能器件。PLMN-13PT:Ho透明陶瓷最突出或最重要的特点是获得最大的二次电光系数((9.37±0.39)× 10−16 m2/V2)。该结果除了具有电学和光致发光特性外，还成为构建多功能器件的有前途的替代方案。

期刊介绍： The Journal of the Spanish Ceramic and Glass Society publishes scientific articles and communications describing original research and reviews relating to ceramic materials and glasses. The main interests are on novel generic science and technology establishing the relationships between synthesis, processing microstructure and properties of materials. Papers may deal with ceramics and glasses included in any of the conventional categories: structural, functional, traditional, composites and cultural heritage. The main objective of the Journal of the Spanish Ceramic and Glass Society is to sustain a high standard research quality by means of appropriate reviewing procedures.
