Our latest work on two-photon-excited fluorescence of single quantum dots is now published in ACS Photonics!
Individual gold nanorods are used to enhance the fluorescence emission of a single quantum dot when it is excited by the absorption of two low energy photons.
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!
