Using Shape to Turn off Blinking for Two-Colour Multiexciton Emission in CdSe/CdS Tetrapods
(2017-05-12)Semiconductor nanostructures capable of emitting from two excited states and thereby of producing two photoluminescence colours are of fundamental and potential technological significance. In this limited class of nanocrystals, ... -
Propagation and Absorption of Light in Planar Dielectric Waveguides with Two-Dimensional Semiconductors
(Optical Soc Amer, 2017-09-12)Strong optical responses of atomically thin two-dimensional (2D) semiconductors make them attractive candidates for integration into various photonic and optoelectronic structures. We discuss some fundamental effects of ... -
Energy Transfer from Colloidal Nanocrystals to Strongly Absorbing Perovskites
(Royal Society of Chemistry, 2018-06-01)Integration of colloidal nanocrystal quantum dots (NQDs) with strongly absorbing semiconductors offers the possibility of developing optoelectronic and photonic devices with new functionalities. We examine the process of ... -
HIF-1α-PDK1 Axis-Induced Active Glycolysis Plays an Essential Role in Macrophage Migratory Capacity
Ultrafast transient pump-probe measurements of thin CH₃NH₃PbI₃ perovskite films over a wide spectral range from 350 to 800 nm reveal a family of photoinduced bleach (PB) and absorption (PA) features unequivocally pointing ... -
Influence of Growth Temperature on Bulk and Surface Defects in Hybrid Lead Halide Perovskite Films
(Royal Society of Chemistry, 2015-12-14)The rapid development of perovskite solar cells has focused its attention on defects in perovskites, which are gradually realized to strongly control the device performance. A fundamental understanding is therefore needed ... -
Chemical Bonding and Defect States of LPCVD Grown Silicon-Rich Si₃N₄ for Quantum Dot Applications
(A V S: Science & Technology of Materials, Interfaces, and Processing, 2014-03)Si-rich Si₃N₄ (SRN) thin films were investigated to understand the various defect states present within the SRN that can lead to reduced performance in quantum dot based devices made of these materials. The SRN films, ... -
Energy Transfer from Colloidal Nanocrystals into Si Substrates Studied via Photoluminescence Photon Counts and Decay Kinetics
(2013-08-16)We use time-resolved photoluminescence (PL) kinetics and PL intensity measurements to study the decay of photoexcitations in colloidal CdSe/ZnS nanocrystals grafted on SiO₂ - Si substrates with a wide range of the SiO₂ ... -
Influence of the Core Size on Biexciton Quantum Yield of Giant CdSe/CdS Nanocrystals
(The Royal Society of Chemistry, 2014-02-06)We present a systematic study of photoluminescence (PL) emission intensity and biexciton (BX) quantum yields (QY_{BX}) in individual "giant" CdSe/CdS nanocrystals (g-NCs) as a function of g-NC core size and shell thickness. ...
