Hour-level persistent luminescence is realized with carbon dots embedded in cyanuric acid, the composition of which is easily obtained by the microwave-assisted heating of carbon dots and urea. By forming donor-acceptor blends, the proposed composition yields intermediate states with long lifetimes, providing a rare-earth-metal-free route to ultralong persistent luminescence.

Metal-organic frameworks (MOFs) with long persistent luminescence (LPL) have attracted extensive research attention due to their potential applications in information encryption, anticounterfeiting technology, and security logic. The strategic combinations of organic phosphor linkers and metal ions lead to tremendous frameworks, which could unveil many undiscovered properties of organics. Here, the synthesis and characterization of a three-dimensional MOF (Cd-MOF) is reported, which demonstrates enhanced blue photoluminescence and a phosphorescent lifetime of 124 ms as compared to the pristine linker (HL) under ambient conditions due to the scaffolding and heavy-atom effects of metal chains in the framework.

Inspired by the natural responsive phenomena, herein the multiple responsive persistent luminescent ZnGaGeO:Ni (ZGGO:Ni) nanoparticles with near-infrared (NIR) II emission peak ≈1330 nm derived from the Ni doping through controlled synthesis based on hydrothermal method are obtained. The obtained NIR II persistent luminescent ZGGO:Ni can not only respond to temperature but also the specific solvent stimulus. The results demonstrate that the NIR II persistent luminescence intensity decreases in hydroxyl containing solvent such as water (HO) and ethyl alcohol (CHO), while the PL intensity remains in solvent without hydroxyl groups such as n-hexane (CH) and deuterated water (DO).

Metal-organic hybrid materials with long persistent luminescence (LPL) properties have attracted a lot of attention due to their enormous potential for applications in information encryption, anticounterfeiting, and other correlation fields. However, achieving multimodal luminescence in a single component remains a significant challenge. Herein, we report two two-dimensional LPL coordination polymers: {[Zn(BA)(BIMB)]·2HO} () and {[Cd(BA)(BIMB)]·3HO} () (BIMB = 1,3-bis(imidazol-1-yl)benzene; BA = butanedioic acid).

With the development of optical anti-counterfeiting and the increasing demand for high-level information encryption, multimodal luminescence (MML) materials attract much attention. However, the discovery of these multifunctional materials is very accidental, and the versatile host suitable for developing such materials remains unclear. Here, a grossite-type fast ionic conductor CaGaO, characterized by layered and tunnel structure with excellent defect tolerance, is found to meet the needs of various luminescent processes.

Mechanoluminescent (ML) materials have shown promising applications in visualized mechanical sensing, imaging, and real-time monitoring because of their unique mechanics-optics conversion. However, the short emission lifetime of transient ML presents challenges in overcoming temporal and spatial constraints in practical applications. In this work, a mechanically charged persistent ML material was created by compositing the CaNaMg(PO):Tb and flexible poly(dimethylsiloxane) (PDMS) matrix.
