文摘
- •
Nanospindle and nanosphere ZnFe2O4 were decorated upon GO by hydrothermal method.
- •
All the samples show superparamagnetism with almost zero coercivity and remanence.
- •
The observed nonlinearity arises due to effective two photon absorption process.
- •
Tuning of NLO behavior with variation in amount of ZnFe2O4 upon GO were achieved.
- •
ZnFe2O4-(15 wt%)GO show higher NLO coefficients and superior limiting actions.
