“…All four ceramics were cut and polished (0.5 mm in thickness) to measure the optical transmittance using a UV-VIS spectrophotometer (UV-2550, Shimadzu, Tokyo, Japan). 3.0/75/25 exhibits the highest transparency around 70% in near-infrared wavelength and 67% at 633 nm wavelength, which is better than the data obtained by most research institutes [7][8][9][10][11][12][13]. The comparison of detailed data is shown in Table 1.…”

“…where n is the refractive index, R is the reflectivity, and is the absorption and scattering index. It has been reported that the value of n can be considered to be a constant when the ratio of PMN/PT is fixed [13]. That means the theoretical optical and such high transparency can fulfill the basic requirements of electro-optical devices.…”

“…Table 1 shows the research progress of PMN-PT transparent ceramics. One can see that the values of optical transmittance are not generally high [6][7][8][9][10][11][12][13]. However, low values can't meet the requirements of application.…”

Relaxor ferroelectric 0.75(Pb 1-3x/2 La x)(Mg 1/3 Nb 2/3)O 3-0.25(Pb 1-3x/2 La x)TiO 3 (La 3+ :PMN-PT x/75/25, where x = 2.8, 3.0, 3.5, and 4.0 mol% of La 3+) transparent ceramics were fabricated by the combination of oxygen atmosphere pressureless sintering and hot-pressing sintering process. The optical transmittances of above four ceramics are higher than 60% at the wavelength of 500-900 nm. La 3+ :PMN-PT 3.0/75/25 exhibits the highest transparency around 70% at 900 nm which is very close to the theoretical transmittance 71%. Each of the four ceramics exhibits the pure perovskite phases. They show fully dense microstructures and their relative densities are higher than 99.8%. The ferroelectric and dielectric measurements indicate that these four ceramics exhibit relaxation characteristics. With increasing La 3+ content, (200) peak in XRD patterns shifts to higher angles and the average grain size increases, while the temperature T max corresponding to the maximum r , the remanent polarizations P r and coercive fields E c decrease gradually.

“…During the photoluminescence process, low energy photons were absorbed while high energy photons were produced. For example, the La 3+ doped PMN-PT ceramics represented a high electro-optic (EO) coefficient on the value of 19.9×10 -16 (m/V) -2 [28,29], and a specific high optical transparency reaches up to 70% [19]. Therefore, the PMN-PT thin films doped with RE ions were expected to be multifunctional optical materials and deserved to be further investigated.…”

Rare earth (RE = La3+, Sm3+, Pr3+) ion doped Pb(Mg1/3Nb2/3)O3-PbTiO3 (RE-PMN-PT) ferroelectric thin films with compositions near the morphotropic phase boundary were grown on the Pt/TiO2/SiO2/Si(100) substrate using sol-gel/spin coating method. The phase structure, electrical properties, and photoluminescence performance of thin films were investigated systematically. The highly (100)-preferred orientation was obtained in pure perovskite Sm-PMN-0.30PT thin films with an average grain size of 131 nm. After 2.5% Sm3+ doping, the PMN-0.30PT thin films exhibited a triple enhancement of dielectric permittivity with a maximum value of 3500 at 1 kHz, a low dielectric loss of 1.3%, and high remanent polarization of 17.5 μC/cm2 at room temperature. In visible light and near-infrared band, the transmittance rate increased with PT content and showed the highest value of 85% in 2.5%Sm-PMN-0.31PT. In addition, the films presented strong red-orange emission at 599 nm, which was sensitively in temperature range of 248–273 K corresponding to the rhombohedral to monoclinic phase transition temperature.

“…Transparent Pb(Mg 1/3 Nb 2/3 )O 3 ‐PbTiO 3 (PMN‐PT) ceramics have attracted attention because their electro‐optic (EO) effect is larger than those of LiNbO 3 single crystals and (Pb, La)(Zr , Ti)O 3 (PLZT) ceramics . However, a low rhombohedral to tetragonal phase transition temperature of 65°C and a low tetragonal to cubic phase transition temperature (Curie temperature) of 155°C at a morphotropic phase boundary composition of 0.67PMN‐0.33PT, where large linear EO effect is obtained, may cause strong temperature dependence of the EO effect and reduce an usable temperature range.…”

0.24Pb(In1/2Nb1/2)O3‐0.42Pb(Mg1/3Nb2/3)O3‐0.34PbTiO3 transparent ceramics were fabricated by a conventional sintering technique. Through optimization of sintering conditions of calcination and sintering temperatures and time, the obtained ceramics showed high optical transmittance of 53% and 71% at light wavelengths of 1300 and 2000 nm, respectively. The ceramics showed a rhombohedral to tetragonal phase transition at ~120°C and a tetragonal to cubic phase transition at 222°C. These transition temperatures were higher than those of 0.67Pb(Mg1/3Nb2/3)‐0.33PbTiO3 ceramics. In addition, the ceramics had a ferroelectric hysteresis loop, a large piezoelectric constant d33 of 407 pC/N, and a planar electromechanical coupling factor kp of 52%. These results suggest that the transparent ceramics may be used as a temperature‐stable, linear electro‐optic material.
