TDPS-QDs Demonstrate Superior Photoluminescence Stability Compared to OA-QDs

As shown in Fig. 7, the PL intensity of TDPS-QDs remains stable at a constant level without significant fluctuations, while the PL intensity of OA-QDs fluctuates greatly. The PL intensity of OA-QDs gradually increases initially, decreases rapidly after 1440 minutes, and ultimately decreases to 55% of the initial value after 2760 minutes. In contrast, the PL intensity of TDPS-QDs remains at 103%. This demonstrates the superior photoluminescence stability of TDPS-QDs compared to OA-QDs.
