Dear A. М. H. Hussein
I hope this email finds you well! I wanted to share some insights on the enhancement of luminescence in quantum dots, as I believe it’s a fascinating topic that could lead to some innovative discussions. There are several key factors that influence their luminescence, such as size and shape, surface passivation, doping, environmental conditions, core/shell structures, and the quality of synthesis. Each of these elements plays a crucial role in determining the efficiency and stability of quantum dots in various applications.
Given the complexity of these factors, I’m curious to hear your thoughts on potential innovative strategies we could explore to further enhance quantum dot luminescence while ensuring their stability. For instance, could we look into novel surface treatments or advanced doping techniques? Or perhaps there are new synthesis methods that could yield better uniformity and performance?
I’d love to brainstorm some ideas together and see what creative solutions we can come up with. Looking forward to your insights!
I would like to mention only two points:
1. In many cases the electrons and holes in the QD have lower energies as compared to the surrounding barriers. Therefore carriers generated in the barriers are collected (captured) in the QD where they recombine. The reemission before recombination is also possible, but by lowering the temperature it becomes less and less probable.
2. In QDs the e-h are forced to be closer, so the exciton binding energy is larger as compared to the bulk material. As a result, thermal destruction of the exciton is less probable. Therefore the emission in QDs is excitonic.
