Summary: The third order nonlinear optical properties of Ni doped ZnMoO4 nanostructures with different concentrations of Ni were investigated. It was found that the absorption edge of the nanostructures shifted slightly towards longer wavelength and an additional absorption band appeared at 440 nm upon Ni doping. The synthesized nanostructures exhibited reverse saturable absorption and negative nonlinearities under the continuous wave laser. The measured third order nonlinear optical susceptibility was approximately 10-6 esu, indicating that the nonlinear optical characteristics of the nanostructures could be controlled by Ni doping and making them a potential candidate for optical device applications.

Summary: By incorporating Ti4L6 (L = embionate) cages and various N,N-chelated transition-metal cations with strong inherent pi-conjugation properties, tight-packed high-performance materials with adjustable nonlinear optical (NLO) effects are achieved. These cage-based ionic pairs exhibit different supramolecular packing structures, including a pi-midline ellipsis pi stacked porous framework with strategically located Ti4L6 cages. Introduction of large pi-conjugated 1,10-phenanthroline type ligands with adjusted aromatic ring electron cloud density effectively regulates their third-order NLO properties, resulting in nonlinear absorption responses from reverse saturated absorption (RSA) to saturated absorption (SA). This work not only presents an extraordinary coordination cage-based assembly, but also provides new insights into the function of cage materials.

Summary: The size-dependent nonlinear optical response of hydrophilic colloidal PbS quantum dots, passivated with thioglycolic acid (PbS/TGA QDs) at different average sizes, was analyzed under 10 ns laser pulses at 532 nm. The study revealed that the key mechanism for nonlinear absorption is the reverse saturable absorption, involving defect trap states in QDs. By forming a SiO2 monolayer on the PbS/TGA QDs surface using MPTMS, the luminescence intensity was significantly increased by 4 to 4.5 times, while the nonlinear absorption coefficient and nonlinear refraction index remained unchanged. These findings demonstrate the implementation of a nonlinear optical response on trap states that are not luminescence centers within the nanosecond probe pulse range.

Summary: The THz modulation performance of the Bi2Te3/Si heterostructure was investigated using THz time-domain spectroscopy under the control of continuous wave lasers at 532 nm and 405 nm. Broadband-sensitive modulation was observed within the frequency range of 0.8 to 2.4 THz. The modulation depth reached 80% under 532 nm laser illumination and 96% under 405 nm illumination. The enhanced modulation depth was attributed to the construction of a type-II Bi2Te3/Si heterostructure, which promoted photogenerated electron and hole separation and increased carrier density dramatically. This work demonstrates the potential of high-efficiency modulation using the Bi2Te3/Si heterostructure and suggests the suitability of UV-Visible control lasers for designing advanced all-optical THz modulators with micro-level sizes.

The primary mechanism for THz emission was identified as shift current, and it was found to depend on the spontaneous polarization direction of the nanosheets. Furthermore, the polarization angle of the pump light could modulate the amplitude and phase of the THz wave, resulting in tunable ellipticity and orientation angle.

Summary: This paper proposes a broadband terahertz radiation source based on a nano-antenna array, and investigates the process of generating terahertz time-domain waves from the nano-antenna array through the hydrodynamic equation of metal plasma. The results show that the polarization of the generated terahertz radiation is perpendicular to the polarization of the incident light, and the emission bandwidth is closely related to the pulse width of the exciting laser. The nano-antenna array is highly designable and integrable, making it promising for integrated terahertz source devices. This study provides a theoretical basis for the future design of terahertz sources based on surface plasmonics.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
