We investigated third-order optical nonlinearities (χ(3)) by Z-scan technique for various heavy-metal oxide (MOX) doped tellurite glasses (TlO0.5-TeO2 matrix; M = Ti, Zn, Ga, Pb and Bi) as well as their relative Raman scattering spectra. As a result, the real part of χ(3) was varied with the Raman shift positions (660~760cm-1) for the peaked Raman intensities, indicating that intermediate structures TeO3+1 close to trigonal bipyramids (tbp) were preferable to increasing Re(χ(3)).
