摘要：

BaAl2O4:EU2+, Dy3+ crystals, which exhibit extremely long lasting phosphorescence peaking at lambda = 500 nm, have been grown successfully by a floating zone technique. Greenish blue phosphorescence from BaAl2O4:Eu2+, Dy3+ crystal was lasting for more than 2 h after the excitation. (C) 1999 Elsevier Science B.V. All rights reserved.
