“…Besides, pure and doped CdS have gathered considerable interest in electronic [10] and non-linear optoelectronic devices [11]. The observation of the third-order nonlinear optical phenomenon is fundamental for optical applications like optical limiting devices, all optical switching and computing, optical correlators and phase conjugators [12,13].…”

“…Nonlinear optical (NLO) materials have recently received considerable attention because of their potential applications in the optoelectronic and all-optical (photonic) devices of telecommunication, optical switching, optical signal processing, optical transmission, optical data storage, optical computing, and so forth, [1,2]. They are also essential for photodynamic therapy, biological imaging, and the protection of human eyes and optical sensors (by NLO materials with optical limiting effects) from high intensity LASER beams [3,4].…”

Nonlinear optical (NLO) properties of organic and metal-organic materials are of considerable interest to emerging optoelectronic and photonic technologies. Much work has been carried out on the former materials but the latter ones have received less attention till date. Herein, a density functional theory (DFT) study on the combined effects of transition metal chelation and solvent polarity on the first hyperpolarizability ( tot ) of 4-methoxyacetophenone thiosemicarbazone (MAPTSC) is reported. MAPTSC exhibits a tautomeric form with higher optical nonlinearity rendering its NLO response in polar solvents potentially switchable. Our results have revealed significant modifications of the first hyperpolarizability of MAPTSC upon complexation with different transition metal chlorides in the presence of solvents with varying dielectric constants. Therefore, its second-order NLO response is highly tunable by the synergy of transition metal chelation and solvent polarity. MAPTSC and its Zn(II) and Pt(II) chloride complexes are promising NLO materials because their gas-phase tot values are larger than those of the prototype push-pull molecules, paranitroaniline (PNA) and urea, by factors of about 1. 40-1.76 and 19.57-37.24, respectively; these factors greatly increase in polar solvent medium. Moreover, they possess high optical transparencies in the visible region of the electromagnetic spectrum which mitigate transparency/nonlinearity trade-offs, thereby increasing the likelihood of broad band NLO response.

Potassium bis(2-methyllactato)borate hemihydrate (KMB) was grown by a solvent evaporation technique. Crystal structural analysis revealed that the potassium cation was pseudo-octahedrally coordinated by five O atoms from four bis(2-methyllactato)borate (MB) ligands and half-occupied water. The sharp peaks in the powder x-ray diffraction (PXRD) pattern confirmed the perfect crystalline nature of the KMB. Transparency was observed in the range from 215 nm to 1100 nm, and the bandgap of KMB was determined to be 2.15 eV. The molecular structure of KMB was established by interpreting the functional group vibrations through vibrational spectroscopy. The molecular structure was further confirmed by the nuclear magnetic resonance (NMR) spectral technique. The peak followed by valley nature observed is due to the self-focusing behavior of KMB. The minimum transmission near the focus in the open aperture curve is attributed to the reverse saturation absorption nature of KMB. The third-order susceptibility (v (3) ) of KMB is estimated to be 4.17694 9 10 À5 esu. These results suggest that KMB can be used in optical sensors as well as other photonic and optoelectronic applications.
