“…These studies indicated that BT ceramics doped with rare-earth may be a promising candidate for MLCC applications. Besides, Battisha et al (2010) reported the up-conversion of infrared light to visible light can be observed in Er/Yb codoped BT ceramics. Cernea et al (2013) observed three distinct peaks (483, 660, and 800 nm) in the BT ceramics doped with Tm under the excitation of 460 nm.…”

The piezoelectric materials, such as ceramics, crystals, and films, have wide applications in the mechanical industry, medical imaging, electronic information, and ultrasonic devices, etc. Generally, adding oxide dopants, or introducing new solid solutions to form the morphotropic phase boundary of the piezoelectric materials were common strategies to enhance the electric properties. In recent decades, rare-earth elements doped piezoelectric materials have attracted much attention due to their multifunctional performances combining piezoelectric and photoluminescence properties, which has potential applications in ultrasonics, electronics, automatic control, machinery and optoelectronic fields. An overview of the recent investigations and perspectives on rare-earth doped piezoelectric ceramics, single crystals, and films were presented.

“…The up-conversion (UC) process from near-infrared to visible is an important approach for a generation of visible luminescence and short wavelength laser actions. Recently, the interest in up-conversion emission has been increased due to the needs for all-solid compact laser devices operating in the blue-green region and the availability of near infrared powerful GaAs/(Al, Ga) as laser diodes that can be used in such systems[I. K. Battisha et al 2010]. The conversion process requires the participation of a luminescent material having multiple energy levels with appropriate energy spacing.…”

Nano-structure BaTi 0.9 Sn 0.1 O 3 (BTSO) doped with Nd 3+ (BTSO: 5N) and co-doped with Nd 3+ /Yb 3+ ions (BTSO: 5NY), were prepared using the modified sol-gel method in powder form and annealed at 1050 o C in air for 4h. Their structural, morphological, photoluminescence and dielectric properties studies were investigated. The crystallite sizes from XRD and TEM found to be decreased upon doping with Nd 3+ and Nd 3+ /Yb 3+ ions, respectively. FTIR results showed enhancement of crystallinity and absence of carbonates upon increasing Yb 3+ ions. TEM micrographs show that particles have spherical shape with small size within the nano-structure phase. FESEM microphotographs showed a density increase due to replacement of Nd 3+ and Yb 3+ ions at the B-site (Ti 4+ ). From photoluminescence it was obtained that emissivity quenched by increasing Yb 3+ ions concentration as the Nd 3+ act as sensitizer for Yb 3+ . Cuire temperature (T c ) of doped and codoped samples shifted to lower values. Besides, their permittivity and AC conductivity increased in comparison with BTSO.

“…1 shows the X-ray diffraction patterns of pure BaTiO 3 (BT) powder, sintered at 750 • C for 1 h. As previously reported in Ref. [17] it is clearly seen that crystallized BT phase can be obtained at heating temperature 750 • C, indicating that one phase tetragonal BT is presented in the prepared BT and BST samples, (referencing to JCPDS files 75-0215 and JCPDS files 79-2265, respectively, for tetragonal phases), which shows well-defined perovskite structure with higher intensity and no detectable secondary phases in the BT pattern [18]. The given data in Table 1 showed that, all the peaks are of tetragonal phase.…”
