Abstract
ZnS nanotetrapods have been synthesized through the directreaction of Zn with S via a thermal evaporation method in Ar at800 °C without catalyst. Studies on the microstructures give experimental evidence for the growthmechanism of ZnS nanotetrapods. A zinc blende (ZB) ZnS core nucleates in the first stageduring the formation of ZnS nanotetrapods; wurtzite twins based on the ZB core then formand lead to the assembly of ZnS nanotetrapod structures. Room-temperaturephotoluminescence properties were also examined, showing a strong green emissioncentered at 495.2 nm.
