Special Issue Information

Dear Colleagues,

Rare earth elements, as important strategic resources, possess unique and excellent optical properties due to their special electronic configuration. Rare earth luminescent materials have been widely used in the fields of lighting, display and detection, and are also gaining greater application value in the fields involving cutting-edge technology and new materials. In the face of low carbon globalization, rare earth luminescent materials have demonstrated higher research significance and application value in the field of functional materials by virtue of their advantages of high efficiency, energy saving and environmental protection. This Special Issue, “Recent Advances in Rare Earth Luminescent Materials”, provides a means of communication between scientists in different disciplines who share a common interest in the materials design, synthesis, optimization, application and luminescence mechanisms of rare earth luminescent materials. We invite original papers and reviews on such subjects as luminescence mechanisms, photoluminescence materials, electroluminescence materials, scintillation crystals, laser crystals, up-conversion luminescence materials, long afterglow luminescence materials, magneto-optic materials, laser materials, optical glass, optical ceramics, etc. Submissions of research on luminescent materials that are not rare earth but have similar luminescence mechanisms, such as luminescent materials with some specific transition metal elements, are also welcome.

Eu3+-doped GdAlO3 (Eu:GAP) and Gd0.5La0.5AlO3 (Eu:GLAP) perovskite single crystals were successfully grown using the optical floating zone (OFZ) method. The microstructure, optical, photoluminescence (PL) and radioluminescence (under X-ray excitation, XEL) were investigated. Under the PL excitation of 275 nm, obvious emission bands peaking at 556 nm, 592 nm, 617 nm, 625 nm, 655 nm, and 706 nm were demonstrated, which correspond to the 5D0 → 7Fj (j = 0–4) transitions of Eu3+. The grown Eu:GAP single crystal showed a stronger PL intensity compared with that of Eu:GLAP in the red light region. After annealing at 1000 °C for 4 h in weak reductive atmosphere (Ar + 5% H2), a slight redshift and dramatic enhancement of PL and XEL intensity occurred. In addition, Eu:GLAP show a more intense XEL emission than that of Eu:GAP. Considering their different densities, these two kinds of red luminescence phosphors are proposed to be promising in a wide field of X-ray imaging, warm white, or plant lighting, respectively.

Deep-red persistent luminescence (PersL) materials have promising applications in fluorescence labeling and tracking. PersL spectral range and PersL duration are considered to be the key factors driving the development of high-performance deep-red PersL materials. To address these two key issues, the performance of PersL materials was continually optimized by doping with cations (Si4+ and Al3+ ions), relying on the material of Li2ZnGe3O8:Cr3+ from the previous work of our group, and a 4.8-fold increase in PersL radiation spectrum intensity and more than twice the PersL duration was achieved (PersL duration up to 47 h). Ultimately, the obtained PersL materials are used to demonstrate their potential use in multi-level anti-counterfeiting, tracking and localization, respectively. This study provides a unique and novel entry point for achieving high-performance PersL materials by optimizing the PersL material host to modulate the electronic structure. Full article

Series of Eu3+/Mn4+/Yb3+-doped SrLa2Sc2O7:Bi3+ (SLSO: Bi3+) were synthesized by a high-temperature solid-state method, and the energy transfer of Bi3+→Eu3+/Mn4+/Yb3+ was observed. Under ultraviolet radiation, a 550 nm emission peak was observed, which is attributed to Bi3+ occupying the Sr2+/La3+ sites. Additionally, the other peaks were found to be 615, 707, and 980 nm, which are assigned to the Re3+ (Eu3+ and Yb3+) and Mn4+ occupying two different cationic sites. An obvious energy transfer (ET) from Bi3+ to Eu3+/Mn4+/Yb3+ was observed, and the tunable color, emitting from yellow to red, was obtained; the ET efficiency was about 86.2%, 78.6%, and 27.5% in SLSO, respectively. We found that the large overlap area between the emission spectrum of the sensitizer and the excitation spectrum of the activator could produce efficient energy transfer, which provided the idea for designing experiments in the future for some highly efficient energy transfer processes.

Near-infrared (NIR) light has attracted considerable attention in diverse applications, such as food testing, security monitoring, and modern agriculture. Herein, the advanced applications of NIR light, as well as various devices to realize NIR light, have been described. Among the diverse NIR light source devices, the NIR phosphor-converted light-emitting diode (pc-LED), serving as a new-generation NIR light source, has obtained attention due to its wavelength-tunable behavior and low-cost. As one of the key materials of the NIR pc-LED, a series of NIR phosphors have been summarized depending on the type of luminescence center. Meanwhile, the characteristic transitions and luminescence properties of the above phosphors are illustrated in detail. In addition, the status quo of NIR pc-LEDs, as well as the potential problems and future developments of NIR phosphors and applications have also been discussed. Full article

The development of novel phosphor materials with excellent performance and modification of their photoluminescence to meet the higher requirements for applications are the essential research subjects for luminescent materials. Multi-site luminescent materials with crystallographic sites for the activator ions that broaden the tunable range of luminescent spectra and even enhance the luminescent performance have attracted significant attention in the pursuit of high-quality luminescence for white light-emitting diodes. Here, we summarize multi-site luminescence characteristics based on the different kinds of host and activator ions, introduce the identifications of multi-site activator ions via optical analysis, provide a structural analysis and theoretical calculation methods, and introduce the regulation strategies and advance applications of multi-site phosphors. The review reveals the relationship between crystal structure and luminescent properties and discusses future opportunities for multi-site phosphors. This will provide guidance for the design and development of luminescent materials or other materials science. Full article
