Fan Nan, Shan Liang, and Xiao-Li Liu et al.

We synthesis uniform Au–CdS core–shell hetero-nanorods and demonstrate the effective plasmon–exciton interaction induced optical nonlinear enhancement in metal–semiconductor hetero-nanostructures. After growing CdS semiconductor shell onto the Au nanorods, the longitudinal plasmon resonance exhibi ... [Appl. Phys. Lett. 102, 163112 (2013)] published Wed Apr 24, 2013.
