摘    要：Förster resonance energy transfer (FRET) is a short-range energy transfer mechanism, which can find many applications, including light harvesting, sensing, nanocrystal characterization, and nm-scale measurement. It can also be used for effective color conversion, which is an important technique for lighting and color-display applications. The study of FRET started with the systems of quasi-zero-dimensional (Q0D) donor and acceptor, such as molecule, protein, and nanocrystal. Then, the FRET from a quasi-two-dimensional (Q2D) donor, i.e., a quantum well (QW), into Q0D acceptors, i.e., the overlaid surface nanocrystals, was reported that stimulated the broad research on the behavior of such a FRET system, aiming at the application of color conversion for further developing the lighting and color display technologies. Recently, the FRET from a Q2D donor inro a Q2D acceptor, i.e., from a QW into another QW, was discovered that might open many new applications. In our study, by growing InGaN/GaN QWs and preparing CdZnSeS/ZnS colloidal quantum dot (QD) solutions, we compare the FRET behaviors between the three systems of QW-to-QW, QW-to-QD, and QD-to-QD energy transfers. Particularly, the dependencies of FRET efficiency on the distance between donor and acceptor in the three systems are carefully studied. The potential applications of those FRET systems are elucidated.
