The absorption spectrum of quantum dots CdSe in FBS solution were measured at different concentrations with different wavelength illuminated, the photobleaching curves of CdSe quantum dots(QDs) were drawed and then fitted with the theory modle. The results showed that the photobleaching process of CdSe QDs in FBS solution is a second order kinetic process. And the photobleaching rate of CdSe QDs is affected by its concentration, higher concentration faster photobleaching, but less affected by the light wavelength. These provided a further favorable evidence to support the photodynamic therapy of using QDs in complex environment.
