Abstract

Core–shell quantum dots suffer from photobleaching by light at wavelengths longer than their emission wavelengths. That is, QD photobleaching can be triggered by photons with low energies that are insufficient to pump electrons into the conduction band. The most probable reason is that electrons are pumped into a surface state and then nonradiatively decayed as in conventional photobleaching.
