    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.…”
