Abstract
We experimentally observe saturable absorption and dra-matic three-photon absorption in various colloidal solutions of cadmium selenide quantum dots, with a strong size dependence witnessed for these properties. We also develop a model for the electronic portion of the nonlinearities that illustrates well the trends exhibited by our experi-mental data. The model incorporates six bands (three each in the va-lence and conduction bands).
