The conventional melt quench technique was used to synthesize the bulk glass of composition 60TeO2.12Bi2O3.18B2O3.10ZnO, and the thin film was deposited by thermal evaporation technique. X-ray diffraction patternreveals the amorphous nature of the material under study. The direct bandgap of as-deposited thin films and bulk glass has been calculated using Tauc’s Plot and found to be 3.0 eV and 2.81 eV, respectively. Nonlinear optical parameters of bulk and thin-film glasses have been estimated using semi-empirical relations. Nonlinear optical susceptibility has found to be 1.272 ×10-13esu (bulk) and 1.810×10-13esu (thin film), respectively. The nonlinear refractive index has been estimated for both bulk (2.733×10-12) and thin-film (3.773 ×10-12). The high nonlinearity of the thin-film is useful as potential applications in optoelectronic devices..
