Abstract

In this paper, the wurtzite-type Zn1−xCrxS nanobelts (NBs) were obtained by a simple hydrothermal process with the ethanol amine as the oriented-assembly agent at 180 °C. The results showed that the Cr3+ ions substituted for the Zn2+ sites in the host zinc sulfide (ZnS), and the maximum concentration of the Cr3+ ions in the ZnS NBs was 4.80 %. The Zn1−xCrxS NBs were constructed by the nanowires, and the growth mechanism of the NBs was investigated in detail. The Zn1−xCrxS NBs showed the ferromagnetism property at room temperature and the magnetic saturation value was increased as the Cr3+ doped ratio increased.
