Highly Efficient Pure‐Blue Single‐Layer Organic Light‐Emitting Diodes Without High‐Triplet‐Energy Auxiliary Materials

Advanced Optical Materials, EarlyView.
Blue organic light‐emitting diodes (OLEDs) comprising triplet‐harvesting emitters require the use of high‐triplet‐energy hosts and blocking layers to confine the triplet excitons to the emitter. Here, we present efficient single‐layer blue hyperfluorescent OLEDs comprising solely of a matrix‐free emissive layer between two charge‐injecting electrodes ...

Material Modification of Borofloat 33 During Scanning‐Based Microforming Using Femtosecond Laser Pulses

Advanced Optical Materials, EarlyView.
Possibilities for ablation‐free microforming of borosilicate glass using ultrashort laser pulses are presented. Depending on the laser parameters and scanning strategy, surface structures with profile heights of up to 20 µm could be produced. The work provides a comprehensive experimental and analytical characterization of the microforming process ...

Broadband Directional Thermal Radiation with Asymmetric Femtosecond Laser‐Processed Surfaces

Advanced Optical Materials, EarlyView.
Femtosecond laser processing is used to scalably create self‐organized angled microstructures which exhibit highly directional emissivity that occurs for all polarizations. Laser parameters are tuned to alter the surface features, control the direction of emission, and enhance the directional emissivity. Electromagnetic modeling is performed to analyze

Using all-sky differential photometry to investigate how nocturnal clouds darken the night sky in rural areas

, 2019
Artificial light at night has affected most of the natural nocturnal landscapes worldwide and the subsequent light pollution has diverse effects on flora, fauna and human well-being. To evaluate the environmental impacts of light pollution, it is crucial

Highly Bright Deep‐Blue Perovskite Light‐Emitting Diodes via Dual‐Passivating Additive‐Based Synergetic Solid‐State Halide Exchange

Advanced Optical Materials, EarlyView.
This study presents a dual‐passivating additive‐based synergetic solid‐state halide exchange (DASH) process using chlorodiphenylphosphine (CDPP), which passivates undercoordinated Pb2+ sites and releases chloride ions for uniform halide exchange. The DASH process enhances halide homogeneity and PLQY, enabling bright and spectrally stable deep‐blue ...
