Summary: This study investigated the mutual influence of two factors - deviation from YAG:Ce stoichiometry and vacuum sintering conditions - on the optical and luminescent properties of ceramics. It was found that deviation from stoichiometry did not affect the morphology and dispersion composition of ceramic powders, but it did have an impact on pore concentration, average grain size, and impurity phases in ceramics. The study also showed that stoichiometry shift led to a shift in the luminescent band maxima and the width of the luminescence bands.

Summary: A yellow emitting long afterglow luminescence material SrSc2O4:Pr3+ was successfully prepared. It exhibits multiple long afterglow luminescence peaks corresponding to Pr3+ f-f transitions, with the afterglow emission falling in the yellow region. The optimal sample doped with 1 at% Pr3+ shows an afterglow luminescence persisting for over 3 hours. Thermoluminescence results indicate the formation of three traps caused by the addition of Pr3+ ions, with the trap density reaching its maximum at 1 at% Pr3+ doping, resulting in the longest afterglow luminescence.

Summary: This study proposes a novel method of using mechanoluminescent visual sensing to fill the gap in originally invisible mechanical behavior in modeling, evaluation and products. In folding tests of flexible electronic films, the method successfully visualizes strain concentration and provides instinctive understanding of complex dynamic mechanical information. Additionally, the mechanoluminescent pattern is influenced by the sticking situation of the flexible film on a folding plate with gripping tape.

Summary: The study found that the shape of the bonding area in cross tension tests can lead to inconsistent stress concentration behaviors and crack growth/peeling behavior, which cause high scattering of CTS values. In contrast, using CT specimens with circular adhesive regions significantly reduced the scattering of CTS values and produced consistent mechanoluminescent patterns. This suggests that mechanoluminescence has the potential to effectively visualize mechanical behavior for optimizing test designs.

Summary: In this paper, sensitive mechanoluminescence phosphors Sr3Al2O5Cl2:Eu2+, Tm3+ were developed and the effect of co-doped Tm3+ ions on ML properties was investigated. The results showed that the ML emission originated from Eu2+ emitting center and the density of shallow traps increased greatly with the increase of co-doped Tm3+ ions, resulting in strong sensitive ML intensity. Additionally, deep traps could provide long time stable ML emission under strong compressive load. These findings indicate the great potential of Sr3Al2O5Cl2:Eu2+, Tm3+ phosphors in the detection of weak stress and long time stable ML.

Summary: A highly stable technique for fabricating n-doped carbon nanotube (CNT) films is reported, where air stability is achieved by completely covering CNTs with n-dopants to prevent oxidation. The introduction of a parylene protective layer allows for air stability for over 365 days, and the n-doped CNTs demonstrate outstanding thermoelectric power generation in strong acids, alkalis, and alcohols. This versatile stabilization technique can be applied to various n-dopants and is expected to be crucial for practical applications of CNT devices.

Summary: In this study, X-ray induced color-tunable long afterglow luminescent material Ca9-xTb(PO4)7:xMn2+ was synthesized and the effects of Mn2+ doping concentration on the properties of the samples were investigated. Efficient energy transfer between Tb3+ and Mn2+ under X-ray excitation was observed, contributing to tunable green-red emission. Increasing Mn2+ concentration led to a decrease in green afterglow emissions of Tb3+ and an increase in red afterglow emissions of Mn2+, resulting in enhanced long afterglow luminescence properties.

Summary: We have developed a novel strategy to design efficient X-ray-induced long afterglow luminescent materials. By using Eu3+ ions as trap creators and emitting centers, and scintillator Bi4Ge3O12 as the host to absorb X-ray efficiently, we obtained excellent X-ray induced red long afterglow luminescence from Bi4Ge3O12:Eu3+ material. The luminescence persisted for more than 5400 s and could still be observed by naked eyes. This strategy provides a pathway for the development of high-performance X-ray induced long afterglow phosphors.
