    Electron Acceleration by Multiple Fast Fermi Reflections at Earth’s Bow Shock by Y. Y. Liu, J. B. Cao, C. M. Liu, Y. T. Song, D. K. Hu

    Published 2025-01-01
    “…Using measurements from the Magnetospheric Multiscale spacecraft, we report unexpected spiky enhancements of energetic electron flux in the upstream region of the Earth’s bow shock. Such enhancements are then demonstrated to result from the accelerated electron population by shock reflection. …”

    Rare Earth Doped Lanthanum Calcium Borate Polycrystalline Red Phosphors by H. H. Xiong, C. Zhu, X. Zhao, Z. Q. Wang, H. Lin

    Published 2014-01-01
    “…The Eu3+ fluorescence in the red spectral region is applied as a spectroscopic probe to reveal the local site symmetry in the host lattice and, hence, Judd-Ofelt parameters Ωt  (t=2, 4) of Eu3+ in the phosphor matrix are derived to be 3.62×10-20 and 1.97×10-20 cm2, indicating a high asymmetrical and strong covalent environment around rare earth luminescence centers. Herein, the red phosphors are promising good candidates employed in white light emitting diodes (LEDs) illumination.…”
