摘要：

Photoluminescence properties under vacuum ultraviolet (VUV, 147 nm) excitation were investigated for a new borophosphate compound. The new phosphor, Sr6BP5O20, has a relatively strong absorption band in a short wavelength region because of the strong covalent characters of B-O and P-O bonds. The phosphor activated by Eu2+ showed a strong blue luminescence. The luminance is about 2.2 times as bright as a commercial blue phosphor, BaMgAl10O17:Eu2+. The phosphor is an attractive candidate of new phosphors for plasma display panels and mercury-free fluorescent lamps. (c) 2005 Elsevier B.V. All rights reserved.
