Lead-free piezoelectric materials with excellent performance are greatly demanded for the environmental issues. The lead-free ferroelectric single crystals are therefore greatly concerned for their much higher piezoelectricity than the polycrystalline counterparts and the domain-tunable property. However, the growth of large size and high-quality lead-free ferroelectric crystals has always been a great challenge. In this work, a ferroelectric KTa 1x Nb x O 3 (KTN) single crystal with an extremely large size of 25 × 25 × 37 mm 3 was grown using the modified top-seeded solution growth method. The large size enabled us to carry out comprehensive investigations on the crystal. The complete sets of dielectric, piezoelectric, and elastic constants for the [001] C -poled KTN crystal with quasi single domain state were determined. Results showed that the crystal exhibits high electromechanical coupling coefficients with k t~0 .642 and k 33~0 .679. Furthermore, the orientation dependence of the piezoelectric, dielectric, and elastic properties was determined by the tensor matrix transformation technique, and the maximum d 33 , s E 33 , and k 33 were found along the polar direction [001] C . This work not only provides important guidance for the growth technology of lead-free ferroelectric crystals but also offers essential datasets of lead-free alkali niobate system, which is of great importance for both theoretical studies and designs of electromechanical devices.

“…Perovkites with a general formula of ABO 3 , such as SrTiO 3 [8,9], BiFeO 3 [10,11] and KTa (1-x) Nb x O 3 [12][13][14], have wide applications in various fields. Among them, SrTiO 3 is kept a watchful eye because of its wide application as a standard substrate in the epitaxial growth of functional films, its use as a photocatalyst in the fields of photochemical water splitting and photocatalysis degradation of organic pollutants, as well as its biomedical applications [8,9,[15][16][17][18].…”

SrTiO 3 :Er 3+ nanofibers were fabricated by the electrospinning process. The phase, microstructure, Doxorubicin loading and release properties, as well as upconversion emission of the fabricated SrTiO 3 :Er 3+ nanofibers were investigated. The X-ray diffraction patterns indicate that the SrTiO 3 :Er 3+ nanofibers have the pure cubic phase. The images of scanning electron microscopy and transmission electron microscopy demonstrate that nanofibers with a porous structure have been obtained. The SrTiO 3 :Er 3+ nanofibers can be used in drug delivery system, which is confirmed by the Fourier transform infrared spectra, results of Barrett−Emmett−Teller measurements and thermogravimetry. Under 808 nm light irradiation, the release process of Doxorubicin in SrTiO 3 :Er 3+ nanofiber shows close relation with the pH value. An acidic condition increases the solubility of the Doxorubicin for the protonated daunosamine group, which accelerates and improves the release of Doxorubicin in SrTiO 3 :Er 3+ nanofibers. In addition, the degree of Doxorubicin release can be manifested by the changing intensity of upconversion emission.
