RETRACTED ARTICLE: Surface Passivation of CdSe Quantum Dots in All Inorganic Amorphous Solid by Forming Cd1−xZnxSe Shell

Scientific Reports, 2017
CdSe quantum dots (QDs) doped glasses have been widely investigated for optical filters, LED color converter and other optical emitters. Unlike CdSe QDs in solution, it is difficult to passivate the surface defects of CdSe QDs in glass matrix, which ...

Growth and reductive transformation of a gold shell around pyramidal cadmium selenide nanocrystals

, 2010
We report the growth of an unstable shell-like gold structure around dihexagonal pyramidal CdSe nanocrystals in organic solution and the structural transformation to spherical domains by two means: i) electron beam irradiation (in situ) and (ii) addition

A Review of Transient Characterization Techniques for Quantum Dot Light‐Emitting Diodes

Advanced Physics Research, EarlyView.
This review surveys transient characterization techniques for quantum dot light‐emitting diodes, including TRPL, TREL, TA, and E‐TA. These methods resolve carrier‐selective dynamics across multiple time scales, enabling direct analysis of charge injection, exciton formation and recombination, efficiency roll‐off, and device degradation.

TiO₂/(CdS, CdSe, CdSeS) Nanorod Heterostructures and Photoelectrochemical Properties

The Journal of Physical Chemistry C, 2012
In this work, nanorods of CdS, CdSe, and CdSeS are deposited by chemical vapor deposition on TiO2 nanorod arrays, and the photoelectrochemical (PEC) perform- ance of the heterostructures is studied comprehensively. It is found that nanorods-shaped CdS are superior to nanoparticles as the photosensitizer. The difference in the photosensitizing effect to

Recent Progress on Fullerene–Based Functional Materials for Energy Conversion

Carbon Energy, EarlyView.
A schematic illustration summarizing the classification, and photo‐/electro‐‐/thermo‐catalysis and energy storage applications of C60 and derivatives. ABSTRACT Efficient energy conversion and environmental protection are still constrained by rapid carrier recombination, unstable interfaces, limited active site, and so on. Owing to the unique electronic

Polarimetry-based analysis of dipolar transitions of single colloidal CdSe/CdS dot-in-rods

, 2014
We prove experimentally, upon polarization analysis performed on a large statistic of single nanoemitters, that high quality core/shell CdSe/CdS dot-in-rods behave as linear dipoles.

Influence of annealing temperature of TiO₂ nanotube array on photoelectrochemical properties of CdSe/TiO₂ heterojunction thin films

Cailiao gongcheng, 2019
CdSe/TiO2 heterojunction thin films were prepared by electrodeposition of CdSe nanoparticles on TiO2 nanotube arrays(TNTs). The effect of annealing temperature of TNTs (200,350,450,600℃) on photoelectrochemical properties of CdSe/TiO2 heterojunctions ...
