摘要：

Inorganic materials are intensively probed for their non-linear optical properties for optoelectronic applications; the synthesis of Ni0.5Zn (0.5-x) MnxFe2O4 nanoparticles for x = 0.15,0.25,0.4,0.5 by co-precipitation method and its structural, morphological, vibrational and third order non-linear optical characterization is reported in this work. The prepared samples belong to a cubic spinel structure with a 15-30 nm crystallite size with a bandgap ranging from 1.6 eV to 2eV. The samples show reverse saturable absorption with a coefficient of the order of 10 10 m/W, a positive nonlinear refraction, and significant optical limiting characteristics. The nonlinear optical response is co-related with linear optical properties.
