It extends the lifetime of originally prepared excited state by 6 orders of magnitude. This has implications for solar energy conversion to photochemical synthesis to optoelectronics to light therapy for cancer Rx. Excitons are the electron/hole pairs formed in semiconductor nanocrystals upon absorption of light, temporarily storing it as chemical energy. In solar cells, for example, excitons transport energy through the material so that it can be collected and converted into electricity.
In terms of photochemistry, the major drawback to using most semiconductor nanocrystals as photosensitizers lies in their short excited st...
