The Impact of Donor‐Orientation on the Emission Properties of Chlorinated Trityl Radicals
Advanced Optical Materials, EarlyView.Chlorinated trityl radicals with electron‐donating groups enable efficient red emission for optoelectronics. Donor orientation and steric constraints regulate vibronic coupling, influencing luminescence. A novel trityl derivative with restricted donor alignment minimizes non‐radiative decay, enhancing quantum yield.

Highly Efficient Upconverted Fluorescence from Coulombically Assembled Ion Pair
Advanced Optical Materials, EarlyView.A dicationic Os(II) complex paired with two monoanionic fluorophores is designed to enable highly efficient triplet–triplet annihilation upconversion, achieving a remarkable upconverted fluorescence quantum yield of 13% at 785 nm excitation with a record‐low threshold intensity of 5.9 mW cm⁻2, attributed to diffusion‐free acceleration of energy ...

Quasirandomness in discrete mathematics, additive combinatorics and group theory
, 2020 The main objective of this bachelor's thesis will be to present the concept of quasirandomness in various mathematical contexts while proving all the pertinent results. We will introduce the results of Fan Chung and Ronald Graham on quasirandom graphs and quasirandom sets, and the results of Timothy Gowers on quasirandom groups.

Advanced Photonics Research, EarlyView.Ultrafast pulsed laser technology enables precise material processing. This study examines molybdenum oxide formation under varying laser parameters. A dataset of 187 samples is generated, and eight deep neural networks (DNNs) with different architectures are trained. Models are validated using three learning rates and evaluated with mean squared error,

Advanced Photonics Research, EarlyView.This work demonstrates the use of reactive laser annealing to selectively tune the epsilon‐near‐zero condition of tin‐doped indium oxide patches integrated in silicon waveguides. This postgrowth annealing technique enables flexible control over the optical constants of transparent conducting oxides (TCOs) at critical telecom wavelengths, paving the way

Digitized Phase‐Change Material Heterostack for Transmissive Diffractive Optical Neural Network
Advanced Photonics Research, EarlyView.A phase‐change‐material‐based digitized heterostack is experimentally demonstrated and theoretically analyzed for future energy‐efficient, fast reconfigured, and compact transmissive diffractive optical neural networks. All‐optical and fully reconfigurable transmissive diffractive optical neural network (DONN) architectures emerge as high‐throughput ...
