Over 30% External Quantum Efficiency Light‐Emitting Diodes by Engineering Quantum Dot‐Assisted Energy Level Match for Hole Transport Layer

Advanced Functional Materials, 2019
In the study of hybrid quantum dot light‐emitting diodes (QLEDs), even for state‐of‐the‐art achievement, there still exists a long‐standing charge balance problem, i.e., sufficient electron injection versus inefficient hole injection due to the large ...

Near-Unity Photoluminescence Quantum Efficiency for All CsPbX3 (X=Cl, Br, and I) Perovskite Nanocrystals: A Generic Synthesis Approach.

Angewandte Chemie, 2019
In a generic synthesis approach, all three CsPbX3 (X=Cl, Br and I) perovskite nanocrystals having near unity quantum yields is reported. This has been achieved by injecting the desired amount of preformed alkylammonium halide salts which acted as a dual ...

Detection of 15 dB Squeezed States of Light and their Application for the Absolute Calibration of Photoelectric Quantum Efficiency.

Physical Review Letters, 2016
Squeezed states of light belong to the most prominent nonclassical resources. They have compelling applications in metrology, which has been demonstrated by their routine exploitation for improving the sensitivity of a gravitational-wave detector since ...

Improving Quantum Efficiency and Thermal Stability in Blue-Emitting Ba2–xSrxSiO4:Ce3+ Phosphor via Solid Solution

Chemistry of Materials, 2018
Ba1.8–xSrxSiO4:0.1Ce3+,0.1Na+ (x = 0–1.8) phosphors were prepared by a high-temperature solid-state reaction. The emission peaks of Ba1.8–xSrxSiO4:0.1Ce3+,0.1Na+ shift from 391 to 411 nm with increasing Sr2+ content under excitation by a UV light at ...
