Abstract
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 s, Inc.
