TAUC DIAGRAM AND Z-SCAN STUDIES FOR NONLINEAR OPTICAL MATERIALS

Abstract

The UV-DRS analysis of Br6 Sn (C6 H5N2)2 (H2O)2 is presented in Fig. 2. The UV-Vis reflectance spectrum shows a sharp absorption edge at 422 nm, which corresponds to the optical transition in the material. The strong absorption in the UV region indicates the presence of π-π* electronic transitions, which are characteristic of the conjugated system present in Br6 Sn (C6 H5N2)2 (H2O)2 .
