The third-order nonlinear optical properties of 1,1'-methylenedipyridinium bis[tetrachloride gold(III)] were investigated by the z-scan method using CW diode laser. The experimental results led to estimation of the nonlinear optical absorption coefficient (β), the nonlinear optical refraction (n2), and third-order nonlinear optical susceptibility (χ 3 ). Our results show that the excited-state absorption cross-sections (σex) is larger than the groundstate absorption cross-sections (σg), this suggests that the nonlinear optical absorption in the MPTC gold(III) is due to the reverse saturable absorption mechanism. Furthermore, the obtained results suggest that our material is considered as a promising candidate for future optical devices applications.

The third-order nonlinear optical properties of the 1,1'-Methylenedipyridinium bis[tetrachloridoaurate(III)] Dimethyl sulfoxide (DMSO) have been studied using Z-scan technique. Measurements were performed with a CW diode laser at 635 nm wavelength and 16.4 mW power.The nonlinear optical absorption coefficient (β) and nonlinear refraction (n 2 )were found at 7.45×10 -4 cm/W and 1.08×10 -8 cm 2 /W, respectively. The nonlinear absorption coefficient β decrease with increase in on-axis input intensity I 0 . The cross-section of the excited state (σ ex ) was found to be larger than the cross-section of the ground state (σ g ). This feature confirmed that the reverse saturable absorption (RSA) mechanism was responsible for the optical limiting effect. The results suggest that this material is considered as a promising candidate for future optical devices applications.

“…For example, as compared with organic polymers, the organic-inorganic compound matrices have more rigidity for inorganic networks and smaller free volume for chromophore dyes, which can help to freeze the chromophore molecules and improve the stability of the materials. As one of the excellent organic-inorganic materials, organically modified silanes (ormosils) are expected to dope functional dyes with the controllable rigidity of the network and the refractive index by simply adjusting the ratio proportion of organic to inorganic component, which makes it has a great potential in modern optical transmission and devices [15][16][17].…”
