The obtained particles were very uniform in size with a diameter of 650±20nm and a shell thickness of 40nm . The temperature dependence of the zero-field cooled magnetizations indicated a broad anomaly at around 110K that was ascribable to the Verwey transition, while the magnetite nanoparticles

At room temperature, the bent NWs demonstrates an enhanced near band edge ultraviolet emission, while the deep level green emission is totally suppressed. Temperature dependent photoluminescence measurements were carried out between 10 and 300 K for both the as-grown and the bent ZnO NWs. It is found that the emission peak energy of the bent NWs systematically shifts to lower energy compared to the as-grown NWs in the whole measured temperature range. Our results indicate that the redshift in the emission peak is related to the uniaxial tensile strain and the enhanced exciton-phonon coupling strength in the bent ZnO NWs.
