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.

Summary: Tailored polymer materials with high-glass transition temperatures, cross-linked matrices, and strong intermolecular interactions containing electric-field poled nonlinear optical (NLO) chromophores are promising for applications in optical telecommunication, high-performance computing, and data transmission. An alternative approach is introduced in which a NLO chromophore is cocrystallized with a polymer, forming a noncentrosymmetric hybrid host-guest complex, creating materials exhibiting second harmonic generation (SHG) properties. The innovative method involves aligning and maintaining a cocrystalline domain orientation through the formation of hybrid host-guest complexes to impart SHG properties.

Summary: An efficient microwave-optical frequency conversion scheme is proposed based on the second-order nonlinearity in the atomic system. The second-order nonlinearity builds up and three-wave mixing process appears due to the magnetic transition driven by a microwave field. It is interesting to find that a detuned auxiliary transition causes a large second-order nonlinearity, which contributes to the increase of conversion efficiency. The simulation results show that the conversion efficiency could be increased by five times. Other effects on the conversion efficiency are also discussed.

Summary: In this work, we successfully extracted the dominant parameters for second-order nonlinear analysis proposed by Hashimoto et al. and demonstrated its effectiveness in a wide frequency range and for FBAR device design. By combining the extracted nonlinear coefficients and driving near the fundamental frequency and half resonant frequency of the FBAR, we were able to reproduce second-order nonlinear characteristics over a wide frequency range. The proposed simulations were also validated against measurement results for various resonators and FBAR filters.

Summary: A series of four new V-shaped binuclear platinum(ii) complexes (D-(pi-Pt-pi-A)(2)) with diphenylpyranylidene ligands as pro-aromatic donors (D) and various electron-attracting groups (A) separated by platinum bis-acetylide fragments have been synthesized, characterized, and studied for their electrochemical, photophysical, and second-order nonlinear optical (NLO) properties. The complexes' NLO responses were determined using the Electric-Field-Induced Second Harmonic (EFISH) generation technique, and their optical properties were rationalized using Time-Dependent Density Functional Theory (TD-DFT) calculations based on a range-separated hybrid. All complexes exhibited positive mu beta(0) values, and their second-order NLO responses could be easily modulated by incorporating various end-capped electron-attracting groups such as malononitrile, indane-1,3-dione, pyrimidine, and pyrimidinium. Notably, complex 7 with a pyrimidinium fragment displayed the highest mu beta(0) value among the series, showing a NLO response twice as high as the mononuclear analogue complex RD2, as confirmed experimentally and theoretically.

Summary: This study investigated the geometric and electronic structures, redox properties, electronic absorption spectra, first hyperpolarizability, and dynamic hyper-Rayleigh scattering response of a series of Ru(II) complexes with polypyridine ligands using density functional theory. The results showed that modifying the ligands had a slight influence on the structures, absorption spectra, and static first hyperpolarizabilities of the complexes, but affected frontier molecular orbitals and charge transfer patterns to some extent. One electron redox significantly affected the properties of the complexes. The study demonstrated a remarkable bathochromic shift and decreased transition energy for the complexes with one electron redox compared to their intrinsic state complexes, indicating enhanced second-order nonlinear optical responses.

Summary: Organic/polymeric second-order nonlinear optical (NLO) materials have played a significant role in laser technology and optical fiber communication, but the intermolecular electrostatic interactions limit their efficiency. Dendrimers and hyperbranched polymers have been proposed as better alternatives for highly efficient NLO materials. Dendronized hyperbranched polymers (DHPs) have shown many advantages in the NLO field, such as easy synthesis, large NLO coefficients, and high orientation stability.

Summary: Second-order nonlinear optical (NLO) materials play a crucial role in photonic devices in the era of information globalization. This study investigates the use of benzocyclobutene (BCB)-based co-polymer as an encapsulating material to improve the temporal stability of NLO materials. The introduction of bismaleimide (BMI) as a curing agent effectively lowers the curing temperature of BCB, preventing the decomposition of doped chromophores during cross-linking. Thermal stimulated depolarization (TSD) results demonstrate that the cross-linked network structure significantly enhances the temporal stability of NLO materials.

It is discovered that intense phosphorescence emission can be achieved in highly polar matrices such as polyacrylic acid (PAA). The dipole-dipole interaction between the polar fluorophore and polar matrix is proposed to stabilize the excited state and facilitate the generation of efficient room-temperature phosphorescence emissions.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
