Cd-free Cu-doped ZnInS/ZnS Core/Shell nanocrystals: Controlled synthesis and photophysical properties
(SpringerOpen, 2018)Here, we report efficient composition-tunable Cu-doped ZnInS/ZnS (core and core/shell) colloidal nanocrystals (CNCs) synthesized by using a colloidal non-injection method. The initial precursors for the synthesis were used ... -
Giant modal gain coefficients in colloidal II–VI nanoplatelets
(American Chemical Society, 2019)Modal gain coefficient is a key figure of merit for a laser material. Previously, net modal gain coefficients larger than a few thousand cm–1 were achieved in II–VI and III–V semiconductor gain media, but this required ... -
Low-threshold optical gain and lasing of colloidal nanoplatelets
(IEEE, 2014-10)Semiconductor nanocrystals, which are also known as colloidal quantum dots (CQDs), are highly attractive materials for high performance optoelectronic device applications such as lasers. With their size, shape and composition ... -
Near-Infrared-Emitting five-monolayer thick copper-doped CdSe nanoplatelets
(WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2019)Doped nanocrystals are instrumental to the high‐performance luminescent solar concentrators (LSCs) and the color conversion devices. Recently, copper (Cu)‐doped three and four monolayer (ML) thick CdSe nanoplatelets (NPLs) ... -
Nonradiative energy transfer between doped and undoped flat semiconductor nanocrystals of colloidal Quasi-2D nanoplatelets
(American Chemical Society, 2019)Atomically flat colloidal semiconductors such as nanoplatelets (NPLs) promise great potential for different optoelectronic applications. Here, we systematically investigate the excitonic energy transfer from colloidal ... -
Orientation-controlled nonradiative energy transfer to colloidal nanoplatelets: engineering dipole orientation factor
(American Chemical Society, 2019)We proposed and showed strongly orientation-controlled Förster resonance energy transfer (FRET) to highly anisotropic CdSe nanoplatelets (NPLs). For this purpose, we developed a liquid–air interface self-assembly technique ... -
Understanding the journey of dopant copper ions in atomically flat colloidal nanocrystals of CdSe nanoplatelets using partial cation exchange reactions
(American Chemical Society, 2018)Unique electronic and optical properties of doped semiconductor nanocrystals (NCs) have widely stimulated a great deal of interest to explore new effective synthesis routes to achieve controlled doping for highly efficient ...
