Mechanical properties of geopolymer-based ultra-high performance concrete with ceramic ball coarse aggregates
Jian Liu,Pengbo Cai,Cheng Liu,Pengfei Liu,Yu Su,Shenchun Xu,Chengqing Wu +6 more
TL;DR: This study investigates the mechanical properties of geopolymer-based ultra-high performance concrete with ceramic ball coarse aggregates, examining the effects of steel fibre content, ceramic ball size and content on compressive, tensile, and flexural strengths, and proposes empirical equations for strength relationships.

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,Weichao Meng,An Xie,Xiaoyan Fu,Hongwu Zhang +9 more
TL;DR: Researchers synthesized Ca9-xTb(PO4)7:xMn2+ phosphors with tunable long afterglow properties via Mn2+ modulation and energy transfer under X-ray excitation, exhibiting efficient energy transfer and excellent afterglow performance even at low-dose radiation.

An optical thermometry based on near-infrared luminescence of LiGaSiO4:Cr3+ phosphors excited by red light
TL;DR: LiGaSiO 4 :Cr 3+ with triple temperature detection function was synthesized in this paper , and the results show that the sample has the best near-infrared luminescence (NIR) performance under the excitation of 620 nm red light when the concentration of Cr 3+ is 0.05%.

From scintillator to phosphor: X-ray induced long afterglow red luminescence from Bi4Ge3O12:Eu3+
Zewen Liu,Tongyan Lin,Naihui Chen,Weichao Meng,Pengbo Cai,Runyao Liu,Xiaoyan Fu,Hongwu Zhang +7 more
TL;DR: Wang et al. as discussed by the authors designed a novel strategy to develop efficient X-ray-induced long afterglow luminescent materials from scintillator to phosphor, which showed that Bi4Ge3O12: Eu3+ can produce excellent x-ray induced red long-afterglow luminance which appeared at 589, 612, 655 and 705 nm corresponding to the 5D0→7Fj(j = 1,2,3,4) transitions, respectively.
