“…The relative dielectric constant ε r of the CeO 2 -doped BTO-KNN materials are found to vary between 150 and 190. The dielectric loss tanδ of the doped BTO-KNN-based ceramics are found to be very low, less than 0.4%, and the ceramic (x=0.75) shows the minimum tanδ (~0.29%) with the highest d 33 of 28 pC/N among the CeO 2 -doped BTO-KNN piezoelectric ceramics, which is higher than those of other reported BLSF systems [6,11] . The increasing in the d 33 can be attributed to the introduction of cerium.…”

The cerium doped 0.9Bi4Ti3O12-0.1K0.5Na0.5NbO3 (BTO-KNN) piezoelectric ceramics were synthesized using conventional solid state processing. The effects of CeO2 doping on the microstructure and the electrical properties of BTO-KNN ceramics were investigated. It is found that the ceramics possess a pure phase of bismuth oxide layer-type structure. The piezoelectric properties of BTO-KNN-based ceramics are significantly improved after cerium doping. The piezoelectric constant d33, dielectric loss tan δ, mechanical quality factor Qm and remanent polarization Pr for the BTO-KNN ceramics with 0.75 wt% CeO2 dopant are found to be 28 pC/N, 0.29%, 2897, 11.83 µC/cm 2 , respectively, and with high Curie temperature TC (~615 °C) and stable piezoelectric properties, demonstrating that the cerium doped BTO-KNN piezoelectric ceramics are the promising candidates for high-temperature applications.

“…We also note that the rare-earth element Pr has been widely used as luminescent centers of inorganic luminescence materials. [15][16][17][18] However, to our knowledge, there are almost no reports on the study of photoluminescent properties of TiO 2 varistor ceramics Whether or not the rare-earth element Pr-doped TiO 2 varistor ceramics can increase the nonlinear coefficient and generate luminescence performance.…”

A series of Pr 6 O 11 (x = 0-0.70 mol%)-doped TiO 2 ceramics were synthesized by the conventional solid-state reaction method. The microstructure, electrical, and luminescence properties were systematically investigated. The results showed that the as-prepared TiO 2 ceramics exhibited strong red emission at 606 nm at room temperature and the optimal photoluminescence were obtained at x = 0.30. In addition, the nonlinear coefficient was improved with the amount of Pr 6 O 11 dopant, reaching the maximum value at x = 0.50. Therefore, Pr 6 O 11 -doped TiO 2 ceramics, which simultaneously exhibited luminescent properties and good electrical properties, would be useful in novel multifunctional devices.

“…Since the 1960s, the series of BLSFs have been intensively studied for their potentially wide applications in dielectric, ferroelectric, piezoelectric, pyroelectric, electrooptic, and photocatalytic and biosensing fields. 1,2,4,5,[15][16][17][18] Many groups confirmed that doping with rare earth elements such as La 3+ , Pr 3+ , Ce 3+ , Nd 3+ , Sm 3+ , Eu 3+ , Dy 3+ , Gd 3+ and Ho 3+ etc. 2,4,5,19,20 could effectively modify BLSFs' electric properties.…”

Er3+ doped SrBi4Ti4O15 (SBT) bismuth layered-structure ferroelectric ceramics were synthesized by the traditional solid-state method, and their upconversion photoluminescent (UC) properties were investigated as a function of Er3+ concentration and incident pump power. Green (555 nm) and red (670 nm) emission bands were obtained under 980 nm excitation at room temperature, which corresponded to the radiative transitions from 4S3/2, and 4F9/2 to 4I15/2, respectively. The emission color of the samples could be changed with moderating the doping concentrations. The dependence of UC intensity on pumping power indicated a two-photon emission process. Studies on dielectric properties indicated that the introduction of Er increased the ferroelectric-paraelectric phase transition temperature (Tc) of SBT, thus making this ceramic suitable for piezoelectric sensor applications at higher temperatures. Piezoelectric measurement showed that the doped SBT had a relative higher piezoelectric constant d33 compared with the non-doped ceramics. The thermal annealing behaviors of the doped sample revealed a stable piezoelectric property. The doped SBT showed bright UC emission while simultaneously having increased Tc and d33. As a multifunctional material, Er doped SBT ferroelectric oxide showed great potential in application of sensor, future optical-electro integration and coupling devices
