摘要：
Hollow-shape colloidal Cu2ZnSnSe4 nanocrystals were successfully synthesized in this study using hot-injection method. TEM, XRD, Raman, XPS, UV-Vis-NIR, and photo response measurements were carried out to characterize the hollow nanocrystals. These hollow nanocrystals were found to have tetragonal structure and high crystallinity, and were Zn-rich in composition. The optical band gap for the hollow Cu2ZnSnSe4 nanocrystals was determined to be about 1.12 eV. The hollow Cu2ZnSnSe4 nanocrystals have potential applications in the photoelectric field.
