Attractive versus repulsive excitonic interactions of colloidal quantum dots control blue-to red-shifting (and non-shifting) amplified spontaneous emission

Cihan, A. F.; Kelestemur, Y.; Guzelturk, B.; Yerli, O.; Kurum, U.; Yaglioglu, H. G.; Elmali, A.; Demir, Hilmi Volkan (American Chemical Society, 2013-11-21)

Tunable, high-performance, two-photon absorption (TPA)-based amplified spontaneous emission (ASE) from near-unity quantum efficiency colloidal quantum dots (CQDs) is reported. Besides the absolute spectral tuning of ASE, ...
Synthesis and characterization of colloidal quantum wells: from simple size-tuned core to complex multi-crown structures

Dede, Didem (Bilkent University, 2018-08)

As a new class of semiconductor nanocrystals, colloidal quantum wells (CQWs), also commonly known as nanoplatelets (NPLs), exhibit remarkable electronic and optical properties that will potentially nd a wide range of ...
