Hello Forum,
how is is possible for quantum dots to offer a wide, broadband absorption spectrum but still have a single distinct emission wavelength?
How is that asymmetry possible?
For example, I would think that if we can absorb, say, 4 wavelengths, we can also emit those say 4 wavelengths...
thanks
