CdSe and CdSe/CdS Nanorod Solids

, 2016
We demonstate the self-organization of CdSe nanorods into nematic, smectic, and crystalline solids. Layered colloidal crystals of CdSe nanorods grow by slow destabilization of a nanocrystal solution upon allowing the diffusion of a nonsolvent into the ...

Zone-Folded Longitudinal Acoustic Phonons Driving Self-Trapped State Emission in Colloidal CdSe Nanoplatelet Superlattices (Letter)

, 2021
Colloidal CdSe nanoplatelets (NPLs) have substantial potential in light-emitting applications because of their quantum-well-like characteristics. The self-trapped state (STS), originating from strong electron-phonon coupling (EPC), is promising in white ...

Electron Transport in Quantum Dot Light‐Emitting Diodes

Advanced Electronic Materials, EarlyView.
This work reveals that electron transport in core/multi‐shell quantum dots is severely hindered by traps located at the core‐shell interface. These traps follow a Gaussian energy distribution with a density of approximately 1023 m−3 and a common energy level of 4.0 eV below the vacuum level.

Photoassisted Synthesis of CdSe and Core−Shell CdSe/CdS Quantum Dots [PDF]

Langmuir, 2004
This paper describes the synthesis of core-shell CdSe/CdS quantum dots (QDs) in aqueous solution by a simple photoassisted method. CdSe was prepared from cadmium nitrate and 1,1-dimethylselenourea precursors under illumination for up to 3 h using a pulsed Nd:YAG laser at 532 nm. The effects that the temperature and the laser irradiation process have on
