Abstract :
CdS hollow nanospheres have been successfully synthesised in the water-ethylene glycol system at room temperature. It is speculated that the formation of hollow nanospheres is an Ostwald ripening process. More importantly, the growth process of the CdS hollow nanospheres has been investigated through microcalorimetry combined with photoluminescence spectra and scanning electron microscope for the first time. The analysis result further proves the formation mechanism of CdS hollow nanospheres.
