Recent advances and prospects for high‐efficiency blue hot exciton organic light‐emitting diodes

FlexMat, EarlyView.
Blue organic light‐emitting diodes (OLEDs) face great challenges in achieving the balance between color purity, device efficiency, and stability. Hot exciton materials offer a solution by rapidly converting non‐emissive triplet excitons into singlet ones through a high‐lying reverse intersystem crossing process.

R package numOSL: numeric routines for optically stimulated luminescence dating

Ancient TL, 2013
In luminescence dating, there are various software packages that can be used to do data analysis, such as Analyst, Java RadialPlotter, SigmaplotTM and so on. There is also an open source R package Luminescence, which has the capacity to tackle not only lots of basic statistical analysis but also provide more advanced data treatment. In this article, we

Bracketing the Age of Freshwater Carbonate Formation by OSL Dating Near Lake Kolon, Hungary

Journal of Environmental Geography, 2014
Freshwater carbonates are unique depositions in the centre of the Carpathian Basin, with debated origin and age. Their formation on the sand covered area of the Danube-Tisza Interfluve is mainly related to lakes appearing in low lying interdune areas ...

Insect communities of late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada

Journal of Quaternary Science, EarlyView.
ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Not too old to rock: ESR and OSL dating reveal Quaternary activity of the Periadriatic Fault in the Alps

Earth, Planets and Space
The Periadriatic Fault system (PAF) ranks among the largest post-collisional structures of the European Alps. Recent geodetic data suggest that a fraction of the Adria–Europe convergence is still being accommodated in the Eastern Alps.

Invisible near‐infrared thermo‐stimulated luminescence from carbon dots enabled by stepwise energy transfer for concealed information encryption

Responsive Materials, EarlyView.
A fully metal‐free near‐infrared (NIR) thermo‐stimulated luminescent system is developed by embedding carbon dots into a carbon nitride matrix and integrating multistage Förster resonance energy transfer. The system exhibits long‐term charge retention, rewritable optical memory, and highly concealed NIR readout, promising for secure data encryption and

Energy levels in YPO4:Ce3+,Sm3+ studied by thermally and optically stimulated luminescence

, 2010
Energy-resolved optically stimulated luminescence (OSL) spectra and thermoluminescence (TL) glow curves of a powder sample of YPO 4:Ce3+,Sm3+ were measured to investigate the nature of the trapping centre and to locate its energy level relative to the ...
