Supplementary material 1 Powder X-ray diffraction (XRD) patterns of O#SQDs produced after
thermal annealing. Those marked with “ ” can be indexed to hexagonal wurtzite ZnO (JCPDS file
no.36-1451), while the others marked with “ ”can be indexed to hexagonal wurtzite-8H ZnS (JCPDS
Card No. 39-1363).

Supplementary material 2
The TEM pictures of O#SQDs synthesized at 200 C for 18 h. The
black circle QDs is the ZnS/ZnO which is amplified.
