Zc. Pu et al., STUDIES ON THE LUMINESCENT PROPERTIES OF EUROPIUM-DOPED ALKALINE-EARTH HALOBORATES, Materials research bulletin, 30(10), 1995, pp. 1227-1234
Europium doped alkaline earth haloborates M(2)B(5)O(9)X : Eu2+ (M = Ca
,Sr,Ba; X = Cl,Br) are synthesized by a high temperature solid state r
eaction. The luminescent properties of these compounds are studied. An
emission shift after X-ray activation is observed and a theoretical e
xplanation is offered for this phenomenon.
