Shm. Poort et al., LUMINESCENCE OF EU2-EARTH IONS IN A ROW( IN HOST LATTICES WITH 3 ALKALINE), Journal of solid state chemistry, 122(2), 1996, pp. 432-435
The luminescence of Eu2+ in Sr-3(PO4)(2):Eu2+, Ba-3(PO4)(2):Eu2+, Ba2M
g(B3O6)(2):Eu2+, and Ba2Ca(B3O6)(2):Eu2+ has been studied. In these st
ructures there are rows of three (large) cations. Emission is observed
from Eu2+ on the central and the terminal sites in these rows, the lo
nger wavelength emission originating from Eu2+ on the central site. Th
is assignment is confirmed by measuring the intensity ratios of the em
ission bands. It fits a model proposed earlier. (C) 1996 Academic Pres
