Researchers at the University of Washington in Seattle in the US say they have seen “blinking” and delayed photoluminescence in copper-doped cadmium selenide nanocrystals for the first time. The new findings provide important insights into the specific roles of the electrons and holes producing intermittent fluorescence in these semiconductors – a process that affects their performance in applications such as fluorescence imaging and light-emitting diodes…..
