Directed emission of CdSe nanoplatelets originating from strongly anisotropic 2D electronic structure
Scott, Riccardo; Heckmann, Jan; Prudnikau, Anatol V.; Antanovich, Artsiom; Mikhailov, Aleksandr; Owschimikow, Nina; Artemyev, Mikhail V.; Climente, Juan I.; Woggon, Ulrike; Grosse, Nicolai B.; Achtstein, Alexander W. Nature Publishing Group (2017)ntrinsically directional light emitters are potentially important for applications in photonics including lasing and energy-efficient display technology. Here, we propose a new route to overcome intrinsic efficiency ... -
Directed Two-Photon Absorption in CdSe Nanoplatelets Revealed by k‑Space Spectroscopy
Heckmann, Jan; Scott, Riccardo; Prudnikau, Anatol V.; Antanovich, Artsiom; Owschimikow, Nina; Artemyev, Mikhail V.; Climente, Juan I.; Woggon, Ulrike; Grosse, Nicolai B.; Achtstein, Alexander W. American Chemical Society (2017)We show that two-photon absorption (TPA) is highly anisotropic in CdSe nanoplatelets, thus promoting them as a new class of directional two-photon absorbers with large cross sections. Comparing two-dimensional k-space ...
