Advanced Optical Materials, EarlyView.Persistent luminescence (PersL), or afterglow, is the phenomenon of light emission that continues long after the excitation source is removed. This review systematically covers the historical development and major material forms of organic PersL materials, detailing their operating principles, mechanisms, and typical applications.

Strong Markov Dissipation in Driven-Dissipative Quantum Systems
Journal of Statistical PhysicsAbstract The Lindblad equation, which describes Markovian quantum dynamics under dissipation, is usually derived under the weak system-bath coupling assumption. Strong system-bath coupling often leads to non-Markov evolution. The singular-coupling limit is known as an exception: it yields a Lindblad equation with an arbitrary strength of ...

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.

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.
