High‐Permittivity Polysiloxanes for Bright, Stretchable Electroluminescent Devices

A high-permittivity, nitrile-functional silicone elastomer for application in stretchable electroluminescent devices is introduced. The polar elastomer emissive layer reaches significantly higher luminance and needs lower operating voltages than an emissive layer based on commercially available PDMS. Besides, the polar elastomer can be used to build...

Wavelength‐Linearly‐Dependent and Polarization‐Sensitive Perfect Absorbers based on Optically Anisotropic Germanium Selenide (GeSe)

The wavelength-linearly-dependent and polarization-sensitive perfect absorbers made by the optically anisotropic GeSe-based and low-cost optical thin film are designed and fabricated. The near-infrared operating wavelength can be modulated not only almost linearly by the thickness of the GeSe layer but also dynamically and finely by the polarization...

Formation of Highly Tunable Periodic Plasmonic Structures on Gold Films Using Direct Laser Writing

Direct laser writing is implemented to produce periodic energy-dependent structures on thin gold films of varying thickness. The morphological changes with pulse energy, film thickness, and grating period are investigated and the beam overlapping effect is discussed in detail. The latter parameters provide an additional degree of freedom for tuning...

Bi‐Functional Chelating Ligand Enables Ultra‐Stable Blue Emissive CsPbBr3 Nanoplatelets Film

This study introduces a novel chelating strategy that utilizes metal manganese ions and multidentate ligands, markedly improving the structural stability and emission efficiency of CsPbBr3 NPLs. The resultant NPLs films demonstrate an impressive PLQY of 66%, showcasing remarkable air stability with consistent blue emission for up to five days. ...

Circular Modulation Pathway of the Afterglow Color in Metal‐Organic Coordination Polymer

Metal-organic coordination polymer with an outstanding circular modulation pathway of afterglow color is constructed based on the concurrence of TADF and RTP, and its afterglow color has the characteristics of temperature dependence, time dependence, forward and reverse excitation wavelength dependence at the same time. Abstract Long-lived...

Vacancy‐Induced Extraordinary Second Harmonic Generation Response for Diamond‐Like Cu3PS4

The lattice vacancies manipulation is realized by introducing the aliovalent Cd atom in Cu3PS4 for the first time. Compared to the Li x Cu3− x PS4, the Cd x Cu3−2 x PS4 displays stronger second harmonic generation (SHG) response gradient enhancement with lattice vacancies content. Eventually, the Cd0.4Cu2.2PS4 possesses a high...
