Long-afterglow metal–organic frameworks: reversible guest-induced phosphorescence tunability

Chemical Science, 2016
We report that two types of Zn-terephthalate (TPA) MOFs (namely [Zn(TPA)(DMF)] (1-DMF) and MOF-5) could exhibit an obvious room-temperature afterglow emission with a time-resolved luminescence lifetime as high as 0.47 seconds.

Sputter deposition of porous thin films from metal/NaCl powder targets [PDF]

, 2019
A method to deposit porous thin films is elucidated. For this purpose, NaCl powder was mixed with a metal powder, cold pressed, and used as a target material in order to deposit a metal/NaCl thin film by DC magnetron sputtering.

Multi‐Level Confinement Single‐Molecule Charge Transfer Activated PRET for Near‐Infrared Targeted Cell Imaging

Advanced Science, Volume 13, Issue 25, 4 May 2026.
The cascade supramolecular assembly of charge‐transfer arrays not only triggered a topological transformation from nanofiber to nanorod and vesicles, but also promoted single‐molecule phosphorescent resonance energy transfer, expanding phosphorescence emission at 500 nm to near‐infrared delayed fluorescence emission at 650 nm with a lifetime of 11.20 ...

Host–guest materials with room temperature phosphorescence: Tunable emission color and thermal printing patterns

SmartMat, 2020
The research of purely organic materials with long afterglow has drawn more and more attention, especially for those with stimulus‐response characteristic. So far, this kind of material is really very scarce and their performance is not good enough.

Battery‐Free UV‐Dose Detector via Defect‐Engineered Ca2SnO4:RE (RE = Sm3+, Pr3+) Oxide Phosphors

Carbon Neutralization, Volume 5, Issue 3, May 2026.
Sm3+/Pr3+‐doped Ca2SnO4 (CSO:RE) phosphors exhibit orange/deep‐red 4f–4 f emissions and defect‐related luminescence. LPL, TL, and OSL measurements reveal thermally/optically addressable traps, with OSL signals retained after 504 h dark storage. Embedded in a polymer matrix, CSO:RE enables battery‐free UV‐dose logging under sunlight with optical readout,
