Exciton emitters in two-dimensional monolayer transition-metal dichalcogenides (TMDs) provide a boulevard for the emerging optoelectronic field, ranging from miniaturized light-emitting diodes to quantum emitters and optical communications. However, the low quantum efficiency from limited light-matter interactions and harmful substrate effects seriously hinders their applications. In this work, we achieve a ∼438-fold exciton photoluminescence enhancement by constructing a Fabry-Pérot cavity consisting of monolayer WS and a micron-scale hole on the SiO/Si substrate.

The generation of radicals through photo-Fenton-like reactions demonstrates significant potential for remediating emerging organic contaminants (EOCs) in complex aqueous environments. However, the excitonic effect, induced by Coulomb interactions between photoexcited electrons and holes, reduces carrier utilization efficiency in these systems. In this study, we develop Cu single-atom-loaded covalent organic frameworks (Cu/COFs) as models to modulate excitonic effects.

Understanding energy transport in semiconductors is critical for the design of electronic and optoelectronic devices. Semiconductor material properties, such as charge carrier mobility or diffusion length, are commonly measured in bulk crystals and determined using models that describe transport behavior in homogeneous media, where structural boundary effects are minimal. However, most emerging semiconductors exhibit nano- and microscale heterogeneity.

Resveratrol (Res), a natural antioxidant widely found in fruits, plays a crucial role in preventing various diseases. However, traditional detection methods usually rely on large amounts of toxic solvents, leading to high costs and potential health risks to researchers. In this work, an economical, green, rapid, and sensitive method for Res detection was developed using banana peel-derived nitrogen-doped carbon dots (BP-N-CDs) as fluorescent sensors.

Constructing a solid solution is an effective strategy for regulating the properties of composite organic semiconductors. However, there presents significant challenges in fabrication and understanding of organic solid-solution semiconductors. In this study, infinite solid-solution semiconductors are successfully achieved by integrating rod-like organic molecules, thereby overcoming the limitations of current organic composite semiconductors.
