Journal ArticleDOI
Spectroscopic and Device Aspects of Nanocrystal Quantum Dots
Jeffrey M. Pietryga,Young-Shin Park,Young-Shin Park,Jaehoon Lim,Andrew F. Fidler,Wan Ki Bae,Sergio Brovelli,Victor I. Klimov +7 more
TL;DR: Recent advances in nanocrystal research related to applications of QD materials in lasing, light-emitting diodes (LEDs), and solar energy conversion are examined.
Journal ArticleDOI
Controlling the influence of Auger recombination on the performance of quantum-dot light-emitting diodes
Wan Ki Bae,Young-Shin Park,Jaehoon Lim,Donggu Lee,Lazaro A. Padilha,Lazaro A. Padilha,Hunter McDaniel,Istvan Robel,Changhee Lee,Jeffrey M. Pietryga,Victor I. Klimov +10 more
TL;DR: This work finds that because of significant charging of quantum dots with extra electrons, Auger recombination greatly impacts both LED efficiency and the onset of efficiency roll-off at high currents, and demonstrates two specific approaches using heterostructured quantum dots.
Journal ArticleDOI
Room Temperature Single-Photon Emission from Individual Perovskite Quantum Dots
TL;DR: It is demonstrated that CsPbX3 quantum dots (X = I, Br) can serve as room-temperature sources of quantum light, as indicated by strong photon antibunching detected in single-dot photoluminescence measurements.
Journal ArticleDOI
Controlled alloying of the core-shell interface in CdSe/CdS quantum dots for suppression of Auger recombination.
Wan Ki Bae,Lazaro A. Padilha,Young-Shin Park,Hunter McDaniel,Istvan Robel,Jeffrey M. Pietryga,Victor I. Klimov +6 more
TL;DR: Results provide direct evidence that the structure of the QD interface has a significant effect on the rate of nonradiative Auger recombination, which dominates biexciton decay.
Journal ArticleDOI
Cavity QED with Diamond Nanocrystals and Silica Microspheres
TL;DR: The observation of the normal mode splitting indicates that the dipole optical interaction between the relevant nitrogen vacancy center and whispering gallery mode has reached the strong coupling regime of cavity QED.
