High-Resolution Bubble Printing of Quantum Dots.
Bharath Bangalore Rajeeva,Linhan Lin,Evan P. Perillo,Xiaolei Peng,William W. Yu,Andrew K. Dunn,Yuebing Zheng +6 more
TL;DR: Bubble printing technique is reported, which exploits a light-generated microbubble at the interface of colloidal QD solution and a substrate to directly write QDs into arbitrary patterns to address the barrier of achieving a widely applicable, high-throughput and user-friendly patterning technique in the submicrometer regime.

Emerging Perovskite Nanocrystals-Enhanced Solid-State Lighting and Liquid-Crystal Displays
TL;DR: In this paper, the performance of liquid-crystal displays (LCDs) and solid-state lighting (SSL) was evaluated with perovskite downconverters. And the fitting-curve effect in calculations and optimizations where simple Gaussian fitting and precise fitting are compared in detail was investigated.

Origin of efficiency droop in GaN-based light-emitting diodes
Min-Ho Kim,Martin F. Schubert,Qi Dai,Jong Kyu Kim,E. Fred Schubert,Joachim Piprek,Yongjo Park +6 more
TL;DR: In this paper, the efficiency droop in GaInN∕GaN multiple-quantum well (MQW) light-emitting diodes was investigated and it was shown that the droop is not related to MQW efficiency but rather to the recombination of carriers outside the MqW region.
