Colloidal synthesis and optical properties of type-II CdSe-CdTe and inverted CdTe-CdSe core-wing heteronanoplatelets

Antanovich, Artsiom ; Prudnikau, Anatol ; Melnikau, Dimitry ; Rakovich, Yury P. ; Chuvilin, Andrey ; Woggon, Ulrike ; Achtstein, Alexander W. ; Artemyev, Mikhail (2015)

We developed colloidal synthesis to investigate the structural and electronic properties of CdSe-CdTe and inverted CdTe-CdSe heteronanoplatelets and experimentally demonstrate that the overgrowth of cadmium selenide or cadmium telluride core nanoplatelets with counterpartner chalcogenide wings leads to type-II heteronanoplatelets with emission energies defined by the bandgaps of the CdSe and Cd...

Temperature dependent radiative and non-radiative recombination dynamics in CdSe-CdTe and CdTe-CdSe type II hetero nanoplatelets

Scott, Riccardo ; Kickhöfel, Sebastian ; Schöps, Oliver ; Antanovich, Artsiom ; Prudnikau, Anatol ; Chuvilin, Andrey ; Woggon, Ulrike ; Artemyev, Mikhail ; Achtstein, Alexander W. (2016)

We investigate the temperature-dependent decay kinetics of type II CdSe-CdTe and CdTe-CdSe core-lateral shell nanoplatelets. From a kinetic analysis of the photoluminescence (PL) decay and a measurement of the temperature dependent quantum yield we deduce the temperature dependence of the non-radiative and radiative lifetimes of hetero nanoplates. In line with the predictions of the giant oscil...
