Carbonized polymer dots with aqueous‐stable room‐temperature phosphorescence: Mechanism, matrix engineering, and application

open access: yesResponsive Materials, EarlyView.
This review focuses on inorganic and organic matrices that enable aqueous‐stable room‐temperature phosphorescence (RTP) in carbonized polymer dots (CPDs). It explains the underlying RTP mechanisms, highlights how matrix engineering provides spatial confinement and bonding interactions to stabilize triplet excitons in water, and demonstrates key ...

A biomimetic phosphor that can build a rigid microenvironment for its long-lived afterglow in aqueous medium

open access: yesCommunications Chemistry
Organic phosphorescent materials have great prospects for application, whose performance particularly depends on the preparation method. Inspired by nature’s wisdom, we report a phosphor that can utilize monomers in its environment by polymerization to ...

Concurrent tunable structural color, luminescence, and afterglow in single ZnS: X@SiO2 spheres via SiO2‐nanoarmor and calcination decoupling collaborative strategy

open access: yesSmart Molecules, EarlyView.
For the first time, tunable structural color, luminescence, and afterglow are integrated into single ZnS:X@SiO2 spheres via a SiO2‐nanoarmor and calcination decoupling strategy, achieving 250–410 nm monodisperse wurtzite spheres with 91% phase conversion, 12.8% PLQY, and 12.27 s afterglow. Abstract The integration of structural color, photoluminescence,

The organics iceberg and the tyranny of organic certification [PDF]

open access: yes, 2013
The existence of an ‘organics iceberg’ is a hypothesis rather than a fact. Nevertheless, reports in The World of Organic Agriculture that there are 37,245,686 certified organic hectares worldwide and that this accounts for 0.86% of global agriculture are

Acidity-activatable upconversion afterglow luminescence cocktail nanoparticles for ultrasensitive in vivo imaging

open access: yesNature Communications
Activatable afterglow luminescence nanoprobes enabling switched “off-on” signals in response to biomarkers have recently emerged to achieve reduced unspecific signals and improved imaging fidelity.

Fire Testing and Hazard Assessment for Flame Retardant Polymer Composites

open access: yesSafety Science and Technology, EarlyView.
Flame retardant polymer composites are now being evaluated with more than pass or fail flammability tests. Heat release, smoke, toxicity, and system‐level behavior are receiving more attention, and multi‐scale methods are being used to describe fire hazard under more realistic conditions.

Photooxidation triggered ultralong afterglow in carbon nanodots

open access: yesNature Communications
It remains a challenge to obtain biocompatible afterglow materials with long emission wavelengths, durable lifetimes, and good water solubility. Herein we develop a photooxidation strategy to construct near-infrared afterglow carbon nanodots with an ...

Effect of Humidity on Ionisation and Ion Chemistry in Active‐Capillary Dielectric Barrier Discharge Ionisation

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 18, 30 September 2026.
ABSTRACT Rationale Dielectric barrier discharge ionisation (DBDI) in an active‐capillary configuration (including the commercial SICRIT source) is widely used as a soft, ambient‐pressure ionisation method for vapours and gases, yet the role of water vapour in controlling reagent ion chemistry and analytical behaviour has not been mechanistically ...
