Summary:
Preparation, characterization and theoretical study of the molecular structure and optical properties of two derived azo dyes. The prepared particles have important optical properties of wide application.
The Z-scan method was adopted to study the optical nonlinear properties of the two compounds using a continuous wave laser beam with a wavelength of 473 nm. Linear refractive indexes on the order of 10 −8 cm 2 / s. We show that the nonlinearity of the two samples is thermal. The two compounds exhibited optical limiter properties with specific cut-off values of 15.5 and 16.7 MW, respectively. The mechanism of the visual limiter shown by the two samples is discussed.
