Resumo |
Two kinds of luminescent centers an observed in BaMgAl10O17:Eu2+ phosphor. Influence of flux on luminescence of Eu2+ in the phosphor is discussed in detail. There exists Eu2+ (F-) center (a luminescent center with 277 nm excitation band and 386 nm emission band) due to the substitution of F- ions for O2- ions, Effective energy transfer from Eu2+ (F-) to Eu2+ (O2-) (a luminescent center with 334 nm excitation band and 450 nm emission band) is observed. The quenching concentration of Eu2+ in BaMgAl10O17 is raised by 0.20 mole per mole host due to forming of new luminescent center Eu2+ (F-). (C) 2001 Elsevier Science Ltd. All rights reserved. |
