Narrowband Organic/Inorganic Hybrid Afterglow Materials

Molecules
Narrowband afterglow materials display interesting functions in high-quality anti-counterfeiting and multiplexed bioimaging. However, there is still a limited exploration of these afterglow materials, especially for those with a full width at half maxima

An Organic Afterglow Protheranostic Nanoassembly [PDF]

Advanced Materials, 2019
AbstractCancer theranostics holds potential promise for precision medicine; however, most existing theranostic nanoagents are simply developed by doping both therapeutic agents and imaging agent into one particle entity, and thus have an “always‐on” pharmaceutical effect and imaging signals regardless of their in vivo location.

A Cocktail Approach Toward Tunable Organic Afterglow Systems [PDF]

, 2021
In this work, a cocktail approach toward tunable organic long-lived luminescence materials in solid, solution, and gel states is proposed. The tunable long-lived luminescence (τ > 0.7 s) is realized by controlling the energy transfer via manipulating the photo-induced isomerization of the energy acceptor (5).

Enhanced Near-Infrared-Excitable Organic Afterglow Nanoparticles for Deep-Tissue Multimodal Imaging via Singlet Oxygen-Mediated Energy Transfer [PDF]

Research
Afterglow imaging offers exceptional signal-to-background ratios (SBRs) by circumventing real-time excitation and autofluorescence, yet conventional systems rely on visible-light excitation, limiting tissue penetration and signal intensity.

Single-component color-tunable circularly polarized organic afterglow through chiral clusterization [PDF]

Nature Communications, 2022
Circularly polarized organic afterglow (CPOA) with both long-lived room-temperature phosphorescence and circularly polarized luminescence is attracting great interest, but the development of multicolor-tunable CPOA in a single-component material remains ...

Unveiling the emission mechanism in analog-doped carbazole-based organic afterglow materials [PDF]

Nature Communications
Afterglow from purely organic solids has drawn increasing attention over the past decade. In carbazole-based systems, recent studies revised earlier aggregation-state explanations and implicated trace carbazole analog impurities as the origin.
