Self‐Assembly of a Tripodal Terpyridine Based Ligand with Luminescent Lanthanide Ions in Solution and Soft Material

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
The tripodal terpyridine‐1,3,5‐benzene tricarboxamide (BTA) ligand 1 is employed in the self‐assembly formation of novel luminescent materials using a range of lanthanide ions. In the polar protic solution, the results from the photophysical measurements are assessed using nonlinear regression analysis, while the functional material properties of the ...

Boundary condition of the volume potential for an elliptic-parabolic equation with a scalar parameter

Electronic Journal of Differential Equations, 2018
Using the descent method for the fundamental solution of the heat equation with a scalar parameter, we find the fundamental solution of the multidimensional Helmholtz equation in an explicit form.

Distributed Bragg Reflector Based on Plasmonic Ag: Plasma Polymer Nanocomposites

Advanced Optical Materials, EarlyView.
This paper presents a comprehensive approach for the optical design and validation of silver nanocomposite‐based Distributed Bragg Reflectors (DBRs). It describes deriving material properties (n, k) and using them to predict the performance of the deposited optical stack, as well as to characterize imperfections in the DBR deposition, or even to ...

The numerical solution of the nonlinear hyperbolic-parabolic heat equation

Discrete and Continuous Models and Applied Computational Science
The article discusses a mathematical model and a finite-difference scheme for the heating process of an infinite plate. The disadvantages of using the classical parabolic heat equation for this case and the rationale for using the hyperbolic heat ...

Terahertz Volume Plasmon‐Polariton Modulation in All‐Dielectric Hyperbolic Metamaterials

Advanced Optical Materials, EarlyView.
THz volume plasmon‐polariton (VPP) propagation through plasmon‐based hyperbolic metamaterials, made of alternating layers of doped and undoped III‐V semiconductors. Abstract The development of plasmonics and related applications in the terahertz range faces limitations due to the intrinsic high electron density of the standard metals.

A parabolic conjugation problem with general boundary condition and a conjugation condition of Wentzel type

Karpatsʹkì Matematičnì Publìkacìï, 2010
We consider the question of existence in Holder class of a solution of an initial-boundary problem for linear parabolic second-degree equation with discontinuous coefficients with a boundary condition and a conjugation condition which are defined by ...

Enhancing Triplet Excitons Lifetime Through Controlled Intermolecular Interactions

Advanced Optical Materials, EarlyView.
Singlet fission (SF) is investigated in pentacene embedded in a surface‐anchored metal–organic framework, enabling a molecular arrangement inaccessible in pure organic crystals. This architecture changes the singlet fission dynamics significantly and enhances the triplet lifetime by almost four orders of magnitude.

Selective Crystal Growth and Optical Responses of 2H and 3R Polytypes in van der Waals Polar Insulator α‐In2Se3

Advanced Optical Materials, EarlyView.
Selective growth protocols are established to obtain high‐quality bulk single crystals of the 2H and 3R polytypes of the vdW polar insulator α‐In2Se3, together with rapid, non‐destructive phase‐identification methods. Combined optical transmission and absolute reflectivity measurements, supported by DFT calculations, reveal distinct polytype‐dependent ...

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
