<table>UV/Vis and PL emission spectra of CdSe/ZnS (core/shell) QDs linked with 1,4-benzenedimethanethiol (BMT) before and after 1 week. [The molar ratio of QDs to BMT: 5 : 1, 1 : 1, and 1 : 3 for samples labeled as Z9D, Z9E, and Z9F, respectively. The (r) shows the repeated measurements of the same sample after 1 week.]</table>
