    UV/VUV switch-driven color-reversal effect for Tb-activated phosphors

    The remarkable narrow-band emission of trivalent lanthanide-doped phosphors excited by the vacuum ultraviolet (VUV) radiation lines of Xe atoms/Xe2 molecules at 147/172 nm are extensively investigated in the deve...

    Synchrotron Photoluminescence Spectroscopy of Boron Nitride Nanotubes with Different Metal Impurities

    In this paper, the impurity influences of BNNTs on photoluminescence (PL) analysis have been investigated systematically. Similar PL spectra were obtained from bulk disk of the cold-pressed BNNTs and dispersed...
