A high‐resolution mechanoluminescence (ML) platform is achieved through chromatic filtration strategy using a conjugated polymer shell (F8BT) on copper‐doped zinc sulfide microparticles. This shell narrows the emission bandwidth, selectively filtering out blue noise, while simultaneously boosting intensity via ML photon recycling process.

Surface Energy‐Confined Multi‐Layer Inkjet Printing for Customizable Optical Microstructures
A surface energy‐confined multi‐layer inkjet printing strategy is developed for customizable fabrication of 3D optical microstructures. By combining interfacial energy confinement with layer‐by‐layer processing, various 3D curved optical microstructures with tailorable morphology, material composition, and spatial configuration are precisely fabricated

Boosting Mechanoluminescence Performance in Doped CaZnOS by the Facile Self‐Reduction Approach
Self‐reduction primarily enhances mechanoluminescence intensity by deliberately introducing lattice defects, which increase structural distortion and amplify the piezoelectric response, thereby improving the force‐to‐light conversion efficiency. Additionally, self‐reduction optimizes the local distribution of Mn2+ ions, promoting energy concentration ...

Modular chromatic number of $C_m square P_n$ [PDF]
A modular $k$-coloring, $kge 2,$ of a graph $G$ without isolated vertices is a coloring of the vertices of $G$ with the elements in $mathbb{Z}_k$ having the property that for every two adjacent vertices of $G,$ the sums of the colors of the neighbors are

The Chromatic Number of Random Intersection Graphs
We study problems related to the chromatic number of a random intersection graph G (n,m, p). We introduce two new algorithms which colour G (n,m, p) with almost optimum number of colours with probability tending to 1 as n → ∞. Moreover we find a range of

By tracking bulk carrier diffusion both vertically and laterally, this study links photoluminescence behavior to crystal quality in CsPbBr3 γ‐ray detectors. Vertical diffusion governs spectral redshift, with high‐quality crystals exhibiting superior transport, while two‐photon microscopy reveals microscale defects that hinder diffusion in low‐quality ...

Challenges of II‐VI and III‐V Blue Quantum Dot Light‐Emitting Diodes
Blue‐emitting electroluminescent quantum dot light‐emitting diodes (QD‐LEDs) face critical challenges that limit their practical application, including short operational lifetimes, low color purity, broad spectral linewidths, and unpredictable transient effects like blinking and positive aging.
