Summary: Second-order nonlinear optical (NLO) materials have significant applications in various fields, and the rational assembly of high-performance second-order NLO materials remains a challenge. In this study, a local polarity-induced assembly strategy is proposed, which involves using specific cations, self-condensation of weakly polarizable units, and introduction of strongly polarizable units to facilitate the assembly of second-order NLO materials. Using this strategy, a variety of excellent second-order NLO materials have been successfully assembled, expanding the sources of such materials.

Summary: This paper reports the stabilization of non-centrosymmetric gamma-NaAsSe2 by doping the As site with Sb, resulting in gamma-NaAs0.95Sb0.05Se2. The single-crystal SHG coefficient of gamma-NaAs0.95Sb0.05Se2 exhibits an enormous value, comparable to that of gamma-NaAsSe2 and approximately 20 times larger than that of AgGaSe2. The bandgap of gamma-NaAs0.95Sb0.05Se2 is similar to that of AgGaSe2, making it highly attractive as a high-performing nonlinear optical material.

Summary: In recent years, there has been a growing interest in the molecular engineering of coordination metal complexes for their applications in nonlinear optics (NLO) in areas such as optoelectronics and optical data storage technology. The control over the optical nonlinearity is induced by the combination of transition metals and organic moieties, which not only enhance the intensity but also significantly affect the polarization of incident laser light. Coordination metal complexes are ideal targets for research due to their robustness, physical and chemical stability, and tunability of NLO responses. This review focuses specifically on small mononuclear metal complexes for NLO applications.

The near-infrared emission of Nd3+ ions was enhanced by Bi3+ ions in the microcrystalline powders doped with various concentrations of Nd3+ ions. The luminescent properties of the powders were studied, and the mechanisms of energy relaxation were discussed.

Summary: The study analyzed the order parameter coupling associated with the first order, improper ferroelastic transition in PbZrO3, showing that the coupling between two order parameters via common strains may contain contributions from higher order terms. The elastic and anelastic properties of the material change as the transition point is approached, exhibiting softening, discontinuous stiffening, and further stiffening in the stability field of the orthorhombic structure. Additionally, the absence of softening due to certain terms implies a slow relaxation time for changes in the order parameters in response to induced shear strain.

Summary: Lead zirconate (PbZrO3) has been a topic of research for many years, with its antiferroelectric properties being questioned recently. It has been found that PbZrO3 doped with Nb exhibits complex domain structures in phases below the Curie temperature (T-C). One of these phases self-organizes at a constant temperature and transforms into a lower phase after several minutes. This isothermal transition was investigated through various measurements, including dielectric, pyroelectric current, and Raman scattering. Discontinuities in permittivity and pyroelectric current were observed, and Raman spectra confirmed the link between these discontinuities and the isothermal transition between two intermediate phases. The ordering process in the lead sublattice, stimulated by thermal fluctuations, is believed to be the driving force behind this peculiar phenomenon.

Summary: Enhanced near-infrared emission at 1531 nm of Er3+ ions excited by Bi3+ and/or Yb3+ ions was observed in Bi3TeBO9:Yb3+/Er3+ phosphors. The synthesis of microcrystalline powders of Bi3TeBO9:Er3+, Bi3TeBO9:Yb3+, and Bi3TeBO9:Yb3+/Er3+ by means of the modified Pechini method was confirmed by XRD measurements. The low phonon energy of the Bi3TeBO9 matrix was revealed by mu-Raman investigations. Energy transfer from Bi3+ ions or Yb3+ ions to Er3+ ions resulted in the enhanced emission at 1531 nm in the Bi3TeBO9:Yb3+/Er3+ system. The potential use of Bi3TeBO9:Yb3+/Er3+ powders as spectral converters in photovoltaic devices was indicated by the results.

Summary: The spectroscopic properties of Eu3+-doped Bi12SiO20 (BSO) were studied and compared with Eu3+-doped Bi12GeO20 (BGO). Luminescence was observed due to the excitation of Eu3+ at the D-5(0) and D-5(1) levels. The Judd-Ofelt theory was used to calculate radiative lifetimes, omega parameters, and other transition probabilities. The strongest luminescence observed was attributed to the D-5(0) -> F-7(0) transition at 578 nm, similar to BGO sillenite.

Summary: We have discovered a low-temperature polar phase in PbZrO3 below 270 K. The temperature dependence of polarization was determined by measuring pyroelectric current changes after poling the single crystal or ceramic in a DC electric field. This phenomenon was observed in both single crystals and ceramics, which may be related to the presence of polar (ferrielectric) antiphase boundaries within the antiferroelectric phase. The transition point was confirmed by changes in domain structure and anomalies in dielectric permittivity and losses in naturally grown single crystals and ceramic samples.

Summary: Intensive investigations have revealed the strong correlation between the piezoelectric properties of PbZr1-xTixO3 (PZT) materials and their ABO(3) perovskite structure, especially at the Morphotropic Phase Boundary (MPB). Undoped PZT single crystals with low Ti content exhibit similar piezoelectric properties to doped PZT ceramics, with a tricritical point observed near x ~ 0.06. These findings provide important insights into the performance of PZT materials.

Summary: A new bromoplumbate organic-inorganic perovskite material exhibiting broad band emission and structural transitions is reported. The emission properties of this material are morphology dependent, with crystals showing whitish emission and thin films showing a dominant excitonic emission. The emission originates from the edges and bulk of the crystals, and the emission peaks are affected by temperature. Additionally, this material exhibits a strong second-harmonic generation (SHG) signal at room temperature.

Summary: The origin of the strong piezoelectric phenomenon in PZT perovskites is still not fully understood. Studies have shown that the enhancement of the piezoelectric properties in this material is related to a change in the distribution of domains with monoclinic symmetry, which are easily polarized and rotated under the action of an electric field.

Summary: The Perovskite solid solutions PbHfO3-PbSnO3 were studied to understand the formation mechanisms of incommensurate phases. The study used x-ray diffuse scattering signal to quantify the evolution of susceptibilities related to different distortion modes. The experimental results showed a linear dependence of ferroelectric stiffness in the cubic phase and a shift in the susceptibility maximum to a nonzero wave vector in the intermediate phase.
