    摘要：Rare earth doped oxyfluoride glass-ceramic （GC）， due to its unique structure and luminescent properties， has shown broad application prospects in multiple fields such as stereoscopic display， fiber laser， laser lighting， near-infrared （NIR） light sources， etc. In this paper， a series of self-crystallized Pr3+/Gd3+/Ce3+ triply doped BaF2 transparent GCs were prepared by the high-temperature melting method. Phase purities， crystal structures， particle morphologies and size distribution of the prepared BaF2∶Pr3+，Gd3+，Ce3+ GC samples were systematically analyzed by X-ray diffractometer （XRD）， XRD Rietveld refinement and transmission electron microscopy， respectively. All results confirm that the BaF2 nanoparticles were formed via a self-crystallization process. Under excitation of 444 nm and 586 nm， the typical visible and NIR emissions of Pr3+ first enhance with increasing Gd3+ concentration to about 3%， and then decrease. This phenomenon is resulted from a significant regulatory effect of Gd3+ dopants on the Pr3+ luminescence. Besides， upon 320 nm excitation， Ce3+ dopants not only emit broadband ultraviolet （UV） emission at 370 nm， but effectively transfer energy to the 1D2 level of Pr3+， thereby inducing the characteristic emissions from Pr3+ 1D2→3H4 transition. Interestingly， the GC samples appear magenta color under illumination of blue light ~444 nm， while show purple color under illumination of UV ~320 nm. In practice， the patterns constructed on copper plates using the GC powders exhibit obvious color switching in connection with excitation lights， successfully verifying their applications in fluorescence anti-counterfeiting and information encryption.

    摘要：Circularly polarized luminescent（CPL） materials， which integrate intrinsic optical chirality and highly efficient luminescence， represent a core class of next-generation functional materials for advanced optoelectronic applications. The development of helical polymer materials has injected renewed vitality into the CPL field. A central challenge remains the rational construction of helical polymers featuring both high luminescence efficiency and large dissymmetry factors. This review systematically summarizes synthetic strategies for CPL-active materials based on helical polymers. The promising applications of these CPL materials are further discussed. Finally， future perspectives and research directions in this dynamic field are proposed， aiming to provide theoretical guidance and advance the development of CPL materials.

    摘要：Heavy metal ions （Fe3+） and dichromate ions （Cr2O72-） pose a serious threat to aquatic ecosystems and human health， and it is urgent to develop efficient and sensitive detection methods. Fluorescent probes based on lanthanide metal-organic frameworks （Ln-MOFs） have attracted much attention in this field. In this study， we used the solvothermal method and 2，2'-bipyridine-4，4'-dicarboxylic acid （H2BPDC） as the ligand to construct two isomorphic new Ln-MOFs， with the molecular formulas of C24H16N6O14Eu2 （CUST-1023） and C24H16N6O14Tb2 （CUST-1024）. Fluorescence spectroscopy studies showed that both could serve as highly selective fluorescent probes for Fe3+ and Cr2O72-， among which CUST-1024 exhibited better sensitivity， with detection limits （LOD， limit of detection） as low as 1.87 μmol/L （Fe3+） and 2.52 μmol/L （Cr2O72-）. Through UV-Vis absorption spectrum， infrared spectroscopy， powder X-ray diffraction， and fluorescence lifetime analysis， it was confirmed that the fluorescence quenching mechanism mainly originated from the effective overlap of the ultraviolet absorption band of the analyte and the excitation spectrum of the MOFs， leading to energy competition absorption and dynamic quenching. This study provides a feasible strategy for designing and synthesizing new luminescent materials for the detection of heavy metal ions and oxygen-containing anions in water bodies. CUST-1023 and CUST-1024 can be used as potential fluorescent sensing materials for detecting Fe3+ and Cr2O72- in water.

    摘要：Quantum-dot superlattices exhibit collective optoelectronic properties originating from ordered interdot packing and enhanced interdot coupling， and are therefore considered a promising material platform for high-performance light-emitting devices. However， translating structurally coherent superlattices into device-compatible patterned thin films remains a key challenge for their application in high-resolution display technologies. Recently， Xu-yong Yang， Tae-Woo Lee， and Yuchen Wu et al. reported pixelated perovskite quantum-dot superlattice light-emitting diodes in Nature. In this work， rhombic dodecahedral CsPbBr3 quantum dots with high geometric symmetry and robust colloidal stability were developed through a ligand-fluoride co-stabilization strategy. Combined with capillary liquid-bridge confined assembly， this approach enabled the fabrication of superlattice thin-film arrays featuring in-plane long-range order， ultrathin vertical confinement and precise spatial patterning. The resulting devices achieved a peak external quantum efficiency of 30.9%， a maximum luminance of 117 144 cd·m-2 and a pixel density of 5 080 pixels per inch， and were further demonstrated in an active-matrix display. This work provides a viable route for applying ordered quantum-dot superlattices in high-resolution display technologies.
