Review of Organic Persistent Phosphors: Classifications by Material Forms, Applications, and Mechanisms

open access: yesAdvanced 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.

Dual‐Emission Switching in a Mn(II)‐Based Hybrid Bromide via Water Coordination: Synthesis, Structure, and Processing

open access: yesAdvanced Optical Materials, EarlyView.
This study reports the synthesis, structure, and optical properties of (pr‐ted)2[MnBr4], a luminescent manganese (II) hybrid halide. It shows green emission under UV and transforms into a red‐emitting hydrated phase with humidity, reversible by heat or vacuum. Structural, photophysical, and theoretical analyses confirm the mechanism.
