Excitation‐Wavelength‐Tunable Lasing in Individual Quantum Dot Superparticles
Advanced Optical Materials, EarlyView.Mesoscale superparticles assembled from CdSe quantum dots are shown to behave as microlasers with emission properties that can be tuned by changing the excitation wavelength. Abstract Microcavities enable precise control over light‐matter interactions, supporting a wide range of applications in photonics and optoelectronics.

Heavy hydrogen in the stratosphere [PDF]
, 2003 We report measurements of the deuterium content of molecular hydrogen (H2) obtained from a suite of air samples that were collected during a stratospheric balloon flight between 12 and 33 km at 40º N in October 2002. Strong deuterium enrichments of up to

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.
Advanced Photonics Research, EarlyView.Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,
