“…Therefore, the excess thermal energy increases the surrounding temperature and generates a temperature gradient. This temperature gradient leads to variation in the refractive index ( n th D ) [41]. In this case, the correlation between the material and the change in the refractive index implies that the greater the thermo-optical coefficient, the greater the refractive index change, resulting in the formation of more SSPM rings.…”

The nonlinear optical (NLO) response of materials is the basis for their use in various applications, including optical switching, optical data storage, and optical limiting. Additionally, it can be used as an innovative method of authentication. In this study, the NLO properties of virgin cherry kernel oil (VCKO) were studied through the observation of spatial self-phase modulation (SSPM) diffraction rings using a 532 nm continuous-wave laser beam. Based on the intensity-dependent number of symmetric diffraction rings, the nonlinear refraction coefficient and thermo-optical coefficient of VCKO were estimated to be 3.81×10-6 cm2/W and 5.34×10-4 K-1 , respectively, for the first time according to the authors' knowledge. Furthermore, we employed the SSPM technique for adulteration detection in the VCKO by analyzing its NLO properties. To accomplish this, we prepared different adulterated samples by mixing VCKO with cheaper commercial oils such as virgin sunflower oil (VSFO) and virgin canola oil (VCO) at various concentration ratios. In mixed VCKO samples that were adulterated, the measured NLO parameters were correlated highly with the amount of adulteration. The results confirm the ability of the SSPM technique to determine the degree of adulteration in oil samples by measuring and comparing their NLO properties. In addition, our results indicate that cherry kernel oil can be a viable candidate as a nonlinear medium for optical applications.

CYHMH crystal was grown using solution growth technique The crystal corresponds to monoclinic structural system with C12/C1 space group (centrosymmetric in nature) and The final cell constants values are a = 24.109 (2) Å, b = 5.5157(4) Å, c = 18.6739(14) Å, β = 110.807(2)°, volume = 2321.2(2) Å. Mechanical studies were measured using Vicker’s hardness tester and n was 1.40, therefore the CYHMH crystals comes under hard materials category. The elastic toughness (stiffness) decreased with increases in applied load. Dielectric permittivity of CYHMH and loss factor were calculated as a function of log frequency. While increasing the temperature the dielectric parameters (dielectric constant, loss, AC conductivity) also increased. The energy required to activate the conductivity were also calculated for higher frequency region.

“…With the rapid development of nonlinear optics, nonlinear optical (NLO) materials are profoundly important in the fields of optical communications, optical machining, ultrafast photonics, etc. − Especially in recent years, materials with third-order NLO properties have been generally used in optical switching, mode-locking systems, laser protection, and other fields. − Compared to conventional third-order NLO materials, which mainly include inorganic and organic materials, such as metal nanoparticles, carbon materials, organic dye molecules, etc., − metal–organic frameworks (MOFs) composed of metal nodes and conjugated organic linkers not only combine the advantages of both inorganic and organic components but also have designable structures and tunable functions, ,− exhibiting fascinating third-order NLO properties. − For example, large conjugated porphyrin-based ligands have been used for the construction of new MOF materials with highly third-order NLO properties. − Moreover, the third-order NLO performances of MOFs have been optimized and improved by assembling MOFs into films, , or by adjusting the types of metal-chelated ligands, constructing interpenetrated networks, and encapsulating guest species .

Achieving metal−organic frameworks (MOFs) with nonlinear optical (NLO) switching is profoundly important. Herein, the conductive MOFs Cu-TCNQ phase I (Ph-I) and phase II (Ph-II) films were prepared using the liquid-phaseepitaxial layer-by-layer spin-coating method and steam heating method, respectively. Electronic experiments showed that the Ph-II film could be changed into the Ph-I film under an applied electric field. The third-order NLO results revealed that the Ph-I film had a third-order nonlinear reverse saturation absorption (RSA) response and the Ph-II film displayed a third-order nonlinear saturation absorption (SA) response. With increases in the heating time and applied voltage, the third-order NLO response realized the reversible transition between SA and RSA. The theoretical calculations indicated that Ph-I possessed more interlayer charge transfer, resulting in a third-order nonlinear RSA response that was stronger than that of Ph-II. This work applies phase-transformed MOFs to third-order NLO switching and provides new insights into the nonlinear photoelectric applications of MOFs.
