Comparison of the Performance of Fluorescent, Phosphorescent, and TADF Luminophores for Explosives Sensing

Advanced Sensor Research
This study investigates how the emission mechanism (fluorescence, phosphorescence, or thermally activated delayed fluorescence, TADF) of a luminescence‐quenching chemical sensor influences the sensitivity of explosives detection.

Light‐Induced Field‐Tunneling Synapses in Solution‐Processed Van Der Waals Heterostructures for Scalable, Retina‐Inspired Optical Sensing

Advanced Functional Materials, EarlyView.
A scalable, solution‐processed WSe2/ZrO2‐x van der Waals heterostructure realizes a light‐induced field‐tunneling synapse (LIFTS) that activates exclusively under bright illumination, emulating the photopic adaptation of the human retina at the device level.

Organic Viticulture in Europe

, 2002
Introduction Organic agriculture is a thriving sector in Europe, and in some countries 10 % of the agricultural area is organic. Not so, however, for organic viticulture: the percentage of organic viticulture land compared to all vineyards is lower than

Improving the Uniformity of Top Emitting Organic Light Emitting Diodes Using a Hybrid Electrode Structure

Advanced Electronic Materials
Some applications of organic light‐emitting diodes (OLEDs) require large area, high light output, and high uniformity. It is difficult to achieve these attributes simultaneously because of voltage drops in the contacts, which cannot easily satisfy high ...

A trade‐off between efficiency and stability in a class of sky‐blue organic light‐emitting diodes

FlexMat
The stability of organic light‐emitting diodes (OLEDs) is a key requirement for their use in commercial displays. One approach to increase the performance of the blue subpixel is to use thermally activated delayed fluorescence (TADF) emitters, which ...
