Summary: Dual-mode and multimode excited nanohybrids of Tm/Yb:NaYF4 upconversion phosphor (UCP) + CsPbX3 (X = Cl/Br/I) quantum dot (QD) glasses were designed using a mechanical mixing and ball milling method. The nanohybrids exhibit a multimode excitation characteristic due to radiation photon reabsorption and no-radiation Förster resonance energy transfer. These nanohybrids can emit polychromatic luminescence from 417 nm to 696 nm under UV light and bluish purple or red luminescence under 980 nm excitation. Practical anti-counterfeiting applications based on these nanohybrids with superior photostability have been successfully realized, demonstrating their great potential in the anti-counterfeiting field.

Summary: Monodispersed nanoscale NaYF4:Ln(3+) nanoparticles with surface-passivated core-shell structures exhibit intense X-ray-charged persistent luminescence and narrow-band emissions tunable from 480 to 1060 nm. The mechanism for persistent luminescence in NaYF4:Ln(3+) is proposed through thermoluminescence measurements and the host-referred binding energy (HRBE) scheme, suggesting the role of lanthanide ions as effective electron traps. These uniform and spherical nanoparticles are dispersible in solvents, enabling new applications such as 3-dimensional optical information storage and inkjet-printing multicolor persistent luminescent nanoparticles.

Summary: The first organic long persistent luminescence (OLPL) system based on carbon dots (CDs) with a duration of over 1 hour has been developed. The CDs-based system, named m-CDs@CA, can be easily fabricated using a household microwave oven and exhibits long persistent luminescence under ambient conditions and even in aqueous media. The successful composition of CDs and CA, the formation of exciplexes and long-lived charged-separated states were confirmed by various characterizations. Covalent bond formation between CA and CDs was found to play a key role in activating long persistent luminescence and preventing its quenching from oxygen and water. This work provides new insights for the development of rare-earth-free and robust OLPL materials.

Summary: This study reports the electron tunneling charging behavior in Cr3+, Sm3+ co-doped near-infrared persistent luminescence material SrGa12O19, allowing for efficient charging by incoherent visible light. The electrons are efficiently captured by nearby Ga-II-O2- electron-hole trap centers via a tunneling process and transferred to shallow traps through a persistently energetic optical pump. The PersL performance is further optimized by engineering the energy band through partial substitution of In3+ for Ga3+. Insights into electron tunneling charging under low-energy excitation for near-infrared persistent luminescence are provided, inspiring more explorations for practical applications.
