    摘要：Three new cyclometalated platinum（Ⅱ） complexes， PtB， PtB-F-2， and PtB-F-1， were designed and synthesized to systematically investigate the influence of fluorine substitution sites on their photophysical and electroluminescent properties. The structures of these complexes were confirmed by 1H/13C NMR and mass spectrometry. Combined experimental characterization and theoretical calculations were employed to elucidate the regulatory effect of fluorine substituents on the photophysical and electrochemical behaviors of the complexes. The results reveal that the substitution position of the fluorine atom has a pronounced impact on the emission spectra. Compared with the non-fluorinated PtB， PtB-F-2 exhibits a red-shifted emission， whereas PtB-F-1 shows a blue-shifted emission. In degassed dichloromethane solutions at room temperature， all complexes display bright green emission in the range of 505-533 nm， with photoluminescence quantum yields of 20.1%-27.2% and lifetime of 1.96-3.87 μs. When applied as the emissive dopants in organic light-emitting devices， the corresponding devices exhibit intense green electroluminescence with maximum external quantum efficiencies （EQEs） of 19.4%-22.2% and maximum luminance values of 24 761-30 316 cd·m-2. Among them， PtB-F-1 and its device demonstrate the best photoluminescent and electroluminescent performance. This study highlights that precise modulation of fluorine substitution sites within the PtB backbone effectively tunes the emission characteristics of Pt（Ⅱ） complexes， offering a feasible molecular design strategy for high-performance organic light-emitting materials and devices.

    摘要：Monoclinic-phase molybdenum dioxide （m-MoO2） two-dimensional （2D） flakes exhibit outstanding properties comparable to those of noble metals， with tunable performance depending on flake thickness. This makes it highly promising for applications in areas such as environmental monitoring and wastewater sensing. One of prerequisites for achieving high-performance MoO2-based devices is the development of an in-situ， rapid， and non-destructive method for measuring flake thickness. In this work， the dependence of the Raman spectra of MoO₂ 2D thin flakes on flake thickness is investigated， providing a method for in-situ， non-destructive thickness characterization. Excited with 532 nm laser， the shift in the Raman characteristic peak at 127 cm-1 effectively reflects the variation in flake thickness. Furthermore， by adjusting the polarization of the excitation light， the crystal axis orientation of the MoO2 thin flake can be calibrated. The Raman spectroscopic results thus offer an effective and convenient approach for monitoring the flake thickness in MoO2-based device fabrication.

    摘要：Inorganic phosphors are widely used in important fields such as solid-state lighting and displays， making them a key focus in the research on luminescent materials. Typically， the design of inorganic phosphors relies on the “crystallographic site engineering”， where activator ions partially substitute suitable metal cations in hosts to form luminescence centers. This strategy requires the inorganic host to provide standard crystallographic sites for activator ions occupancy； otherwise， it is difficult to realize effective doping and subsequently efficient luminescence. In recent years， it has been discovered that even in some hosts lacking standard substitution sites， efficient luminescence can be achieved when activator ions enter interstitial crystallographic sites， leading to the development of interstitial luminescent materials. This review systematically summarizes the construction and characterization of interstitial luminescence centers， and the synthesis and application of interstitial phosphors， while also discussing the opportunities and challenges in future research. The construction of interstitial luminescence centers not only provides a new perspective for developing inorganic phosphors but also holds significant importance for exploring and understanding novel luminescence properties in existing phosphors.

    摘要：Scintillators， serving as core conversion materials for high-energy radiation detection and imaging， play an indispensable role in medical imaging， security inspection， industrial non-destructive testing， and high-energy physics. Although traditional rare-earth ion-doped scintillators （e.g.， Tb3+， Eu3+） exhibit excellent performance， they face challenges such as high raw material costs and narrow emission bands. Non-rare-earth-activated inorganic glass scintillators have emerged as a research focus for the next generation of radiation detection materials， owing to their wide range of activators， broadband emission， and strong environmental adaptability. This article systematically reviews the luminescence mechanisms and recent advancements in such materials， with an in-depth discussion of major material systems， including transition metal ion doping （e.g.， Mn2+， Cu+， Sn2+）， oxide nanocrystal-embedded glass， and novel perovskite glass （lead-based， manganese-based， copper-based）. Innovative strategies in sensitized energy transfer， in-situ crystallization control， halogen coordination engineering， and fiber array fabrication are detailed， along with significant improvements in key performance indicators such as light yield （up to 425% of BGO）， spatial resolution， and thermal quenching resistance （63% intensity retention at 573 K）. The review also highlights existing challenges， including the gap between achieved and theoretical light yields， the trade-off between high crystallization rates and optical homogeneity， insufficient long-term radiation stability， and the need for lead-free alternatives. Future research should focus on multi-scale structural modulation， defect engineering， lead-free design， and device integration technologies to facilitate the practical application of non-rare-earth glass scintillators in advanced medical imaging， industrial non-destructive testing， and extreme environment detection.
