Blue emission from CaYAl3O7:Ce(CYACe) excited by thermal, electronic and mechanical energy is reported in this letter. This finding may be applied as a guide in designing self-power optical sensors with direct applications inpharmacology, in situ biomedical monitoring and diagnostics. The results revealed that the emission bands of afterglow (AG), electroluminescence (EL) and mechanoluminescence (ML) are similar, located at 421 nm, which indicated that all the emissions are emitted from the same center of Ce3+. Furthermore, we can explain the electro-mechano-optical luminescence of CYACe using a model of the excitation of trapped electrons released by different energy sources (C) 2011 The Electrochemical Society.

Long afterglow yellow luminescence from Pr3+ doped SrSc2O4

Xiaoyan Fu, Shenghui Zheng, Yanfeng Meng, Wenzhi Sun, Hongwu Zhang

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.

Improvement in laser-based micro-processing of carbon nanotube film devices

Daichi Suzuki, Daniela Serien, Kotaro Obata, Koji Sugioka, Aiko Narazaki, Nao Terasaki

Summary: In this study, the potential and application of laser-based micro-processing for patterning CNT films were assessed. It was found that this method can pattern micrometre-thick CNT films in micrometre spatial resolution and directly pattern the CNT films inside the protective film, which is not achievable by other processing technologies.

Selective detection of microcracks under the surface of glass substrates by non-contact stress-induced light-scattering method with temperature variations

Yoshitaro Sakata, Nao Terasaki

Summary: In this study, a novel non-contact thermal stress-induced light-scattering method (N-SILSM) is proposed for detecting polishing-induced microcracks on the surface of glass substrates. Microcracks and tiny particles can be distinguished and measured using temperature variation. This method contributes to improving the quality of glass substrate manufacturing and reducing defects.

Mechanoluminescence visual inspection of microcrack generation through fatigue process in flexible electronic films

Nao Terasaki, Nao Ando, Kei Hyodo

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.

Mechanoluminescent study for optimization of joint design on cross tension test

Nao Terasaki, Yuki Fujio, Shin Horiuchi, Haruhisa Akiyama, Masami Itabashi

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.

Sensitive mechanoluminescence from Eu2+, Tm3+co-doped Sr3Al2O5Cl2 phosphors

Wei Meng, Pengbo Cai, Xiaoyan Fu, Hongwu Zhang

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.

Outstanding Robust Photo- and Thermo-Electric Applications with Stabilized n-Doped Carbon Nanotubes by Parylene Coating

Daichi Suzuki, Yoshiyuki Nonoguchi, Kazumasa Shimamoto, Nao Terasaki

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.

Soft X-ray induced color-tunable long afterglow phosphors Ca9-xTb(PO4)7: xMn2+based on Mn2+modulation and energy transfer

Tongyan Lin, Zewen Liu, Naihui Chen, Runyao Liu, Jiaxu Zhang, Pengbo Cai, Wei Meng, An Xie, Xiaoyan Fu, Hongwu Zhang

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.

From scintillator to phosphor: X-ray induced long afterglow red luminescence from Bi4Ge3O12:Eu3+

Zewen Liu, Tongyan Lin, Naihui Chen, Wei Meng, Pengbo Cai, Runyao Liu, Jiaxu Zhang, Xiaoyan Fu, Hongwu Zhang

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.
