The luminescence of Eu2+ in Ba2SiO4, Sr2SiO4, KBaPO4 and KSrPO4 has be
en studied. Luminescence measurements in the temperature range from 4.
2 K to 550 K were performed and gave detailed information on the lumin
escence properties of divalent europium on both sites available in the
orthosilicates. Based on the results on the Eu2+-activated orthophosp
hates and on a model proposed earlier we are able to assign and to exp
lain the different emissions of Eu2+ on these two sites. (C) 1997 Else
