Our latest work on two-photon-excited fluorescence of single quantum dots is now published in ACS Photonics!
In a nutshell, we showed more than 10000-fold enhanced fluorescence of a single semiconductor quantum dot using a two-photon-excitation scheme. The high enhancement of this nonlinear effect arises mainly from the local field amplification at the tip of the nanorod. For more details, see the paper.
Congratulations to all the authors!
