“…(Figure 5a). Most strikingly, the magnitude of dielectric enhancement (Δ𝜖′ r ) in 1 reaches up to ≈250%, which is higher than traditional inorganic perovskite materials such as BaTiO 3 (Δ𝜖′ r = 17%), [24,25] SrTiO 3 (Δ𝜖′ r = 100%), [26] BaCoSiO 4 (Δ𝜖′ r = 100%), [27] SLTO-CMNO (Δ𝜖′ r = 40%), [28] 6Pb(Sc 1/2 Nb 1/2 )O 3 -61Pb(Mg 1/3 Nb 2/3 )O 3 -33PbTiO 3 (6PSN-61PMN-33PT, Δ𝜖′ r = 100%), [29] and (1x)Ba 0.85 Ca 0.15 Zr 0.1 Ti 0.9 O 3 -(x) Ca 3 Co 4 O 9 (BCZT-CCO, Δ𝜖′ r = 60%) [30] (Figure 5b). This result indicates strong response for single-crystal-based dielectric devices of 1, which reveals its promising potential for practical applications.…”

Stimuli‐responsive materials, showing bistable behaviors between two distinct states under external stimuli, can be potentially applied as basic components of modern electrical and electronic devices. 2D hybrid perovskites hold a promise to switch and tune dielectric bistability based on their solid‐state phase transitions. Here, strong dielectric enhancements are successfully actualized by virtue of light illumination in a Dion–Jacobson (DJ) type 2D hybrid perovskite, (HDA)(MA)2Pb3Br10 (1, where HDA is 1,6‐hexanediammonium and MA is methylammonium). Upon heating, 1 exhibits an ordered–disordered phase transition ≈ 324 K (Tc), accompanying a transition from its low to high dielectric state. Strikingly, its light‐induced dielectric constant changes are greatly enhanced with a magnitude up to 250% near the Tc, superior to most traditional inorganic phase transition materials. This process closely relates to the photoexcited dielectric effect that is caused by the interband photo‐excitation. Benefitting from the stability of DJ‐type perovskite structure, the switching cycles of dielectric enhancement display operational stability with superior anti‐fatigue characteristics. As per the knowledge, the findings of this strong dielectric enhancement are unprecedented in the family of 2D DJ‐type hybrid perovskites, which will facilitate broad interest in exploiting new stimuli‐responsive materials to assemble high‐performance smart electronic devices.

“…To overcome these shortcomings and improve the Tc and the Tr-t, Pb(Sc 1/2 Nb 1/2 )O 3 (PSN) was introduced into the PMN-PT because its Tc that is much quite higher than that of PMN [11][12][13][14][15][16]. A relatively high phase transition temperature (Tc > 200 • C) has been reported in PSN-PMN-PT single crystals at the MPB, with good piezoelectric d 33 (1260~1550 pC/N) [16].…”

“…Therefore, we speculate that ternary PSN-PMN-PT crystal will have higher optical damage-resistance properties than PMN-PT crystal, indicating its potential application prospect in the optical field. At present, most studies focus on these crystals' electrical properties [11][12][13][14][15][16]. No study has yet focused on the optical properties of the ternary PSN-PMN-PT crystal, which are detrimental to the design of optical devices and the development of multifunctional materials.…”

This study investigated the optical properties and the interband transition of a ternary [100]-oriented 6PSN-61PMN-33PT relaxor ferroelectric single crystal. Compared with the binary [100]-oriented PMN-32PT crystal, the [100]-oriented 6PSN-61PMN-33PT crystal exhibited excellent optical properties, including high transmittance, low refractive index, weak frequency dispersion, and low reflection and absorption coefficients. All these differences can be attributed to the structural changes of the 6PSN-61PMN-33PT crystal, such as its large lattice size and increased band gap. The crystal’s transmittance was significantly improved after alternating current electric field poling due to the increased domain size and the order domain structure. The largest transmittance for the 6PSN-61PMN-33PT crystal was up to 66%. Our experimental results indicate that the ternary 6PSN-61PMN-33PT ferroelectric single crystal has great application potential in the optical field.

Simultaneous Photo‐Induced Magnetic and Dielectric Switching in an Iron(II)‐Based Spin‐Crossover Hofmann‐Type Metal‐Organic Framework

Molecular materials possessing photo‐tunable polarization switching is promising for optical switches, smart sensors, and data storage devices. However, it is challenging to devise a molecular material featuring simultaneous switchable magnetic and dielectric properties with regard to non‐invasive and convenient light stimulus. Herein, we report a new Hofmann‐type metal–organic framework (MOF) {Fe(bpt)[Pt(CN)4]} ⋅ 0.5anth (1, bpt=2,5‐bis(4‐pyridyl)thiophen; anth=anthracene), which displays thermo‐ and photo‐switchable magnetic and dielectric properties. Photo‐monitored structural analyses revealed that it was the photo‐induced deformation of FeII coordination sphere and relative movement of guest anthracene that resulted in the variation of the local electric dipoles. These findings provide a new strategy to realize polarization switching through the light‐induced spin crossover, and would be of fundamental significance for future photo‐switchable and multifunctional materials.
