Red‐to‐Blue Upconversion Nanoparticles Catalyze Aqueous Radical Polymerization
Advanced Optical Materials, EarlyView.Encapsulation of a red‐to‐blue upconversion pair into polymer nanoparticles gives water‐stable heterogeneous nanocatalysts with distinguished stability. Red light irradiation of these nanocatalysts initiates aqueous polymerization of a series of acrylates with high conversion yields.

Infrared Colloidal Quantum Dot Edge Emitting Lasers Integrated on Silicon
Advanced Optical Materials, EarlyView.In this work, the first monolithic integration of Pb‐chalcogenide CQDs in an edge‐emitting DFB laser cavity onto a Si/SiO2 substrate has been demonstrated. The optimizations of SiO2 layer thickness, engineering of the grating duty cycle, and implementing λ/4 phase shift resulted in the achievement of spectrally pure, single‐mode lasing at 1650 nm with ...

Incorporating Si into Sb2Se3: Tailoring Optical Phase Change Materials via Nanocomposites
Advanced Optical Materials, EarlyView.We study the structural, optical, and thermal effects of adding silicon to Sb2Se3 and demonstrate that the as‐deposited solid solution phase segregates after electro‐thermal switching, creating a nanocomposite with effective‐medium properties and a phase‐change response.

Vat Photopolymerized HEMA/HEA Hydrogels for Solvent‐Responsive Transparency and Optical Encryption
Advanced Optical Materials, EarlyView.Vat‐photopolymerized HEMA/HEA hydrogels exhibit reversible transparency‐opacity switching via hydration‐induced microphase separation and solvent exchange. The printed materials enable hydration sensing, optical encryption, and information storage, while maintaining high ductility and reversible rheology.

Photonics of Topological Magnetic Textures
Advanced Optical Materials, EarlyView.Localized noncollinear magetic textures imprint their geometry and topology onto traversing photonic fields endowing them with orbital angular‐momentum, chirality, and magnetoelectric densities. Abstract Topological textures in magnetically ordered materials are an important case studies for fundamental research with promising applications in data ...
