Sm-Doped PIN-PMN-PT Transparent Ceramics with High Curie Temperature, Good Piezoelectricity, and Excellent Electro-Optical Properties

Abstract

Transparent piezoelectric materials are capable of coupling several physical effects such as optics, acoustics, electricity, and mechanical deformation together, which expands applications for mechanical-electro-optical multifunctional devices. However, piezoelectricity, transparency, and Curie temperature restrict each other, so it is difficult to achieve high piezoelectricity with both good transparency and a high Curie point. In this paper, Sm-doped 24Pb(In 1/2 Nb 1/2 )O 3 -42Pb(Mg 1/3 Nb 2/3 )O 3 -34PbTiO 3 (PIN-PMN-PT) transparent ceramic with a high piezoelectric coefficient of 905 pC/N, excellent electro-optical coefficient of 814 pm/V, and high Curie-point of 179 °C is fabricated. Sm doping effect on the phase structures, piezoelectricity, ferroelectricity, optical transparency, electro-optical properties, and thermal stability is systematically investigated. Compared with PMN-PT transparent ceramics, PIN-PMN-PT transparent ceramics exhibit better temperature stability. Electro-optical modulation and energy conversion are achieved using PIN-PMN-PT transparent piezoelectric ceramic, which indicates that it has great potential to develop mechanical−electrical−optical multifunctional coupling devices for optical communication, energy harvesting, photoacoustic imaging, and so on.

Systematic review of the osteogenic effect of rare earth nanomaterials and the underlying mechanisms

“…Due to the piezoelectric properties of RE materials, the use of RE ions as dopants can increase the piezoelectricity of a material. The incorporation of Eu [ 47 ] and Sm [ 48 ] dopants into the PMN-PT ceramic system, for instance, increases piezoelectricity. RE doping generates electrostatic interactions (such as H-bonding) [ 49 ] and stabilizes the crystal structure of NPs, which decreases their dielectric constant, in turn facilitating the distribution of polarized electric fields on the NP surface for increased composite piezoelectricity [ 45 ].…”

Transparent high-performance piezoceramics through pressureless sintering

“…However, achieving both piezoelectricity and transparency in ceramics is challenging because they are generally conflicting, as exemplified in (Pb,La)(Zr,Ti)O 3 (PLZT) ceramics [15,16]. To overcome these challenges, extensive efforts have been made to develop materials with both transparent and piezoelectric properties.…”

“…and B 2 represents high-valence cations (such as Nb, Sb, Ta, etc. ), are usually selected as a third component to be introduced into a BS-PT system due to their excellent dielectric and piezoelectric properties [11][12][13]. The introduction of relaxor ferroelectric end members not only improves the relaxor characteristics and electrical properties, but also can form a ternary solid solution formed with the BS-PT system, and extend its MPB region from a point to a line, which can achieve performance regulation in a wider range.…”
