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.

Influence of Platinum Thin Films on the Photophysical and Quantum Properties of Near‐Surface NV Centers

Advanced Optical Materials, EarlyView.
This work investigates the impact of platinum thin films on shallow nitrogen‐vacancy (NV) centers in diamond for quantum sensing applications. Five samples are analyzed with varying nitrogen implantation energies (2.5–60 keV) and changes in optical properties, charge state, and coherence times are reported.

Electroluminescence and Franz–Keldysh Modulation Observed in Sn/Ge Multi‐Quantum Wells

Advanced Optical Materials, EarlyView.
We investigate the optoelectronic properties of PIN diodes based on ultrathin α‐Sn/Ge multiple quantum film structures, fabricated by molecular beam epitaxy, both experimentally and theoretically. The samples exhibit a light emission spectrum in the short‐wavelength infrared range with two transitions. Furthermore, when operating as a photodetector, we
