Crystal Structures and Properties

Dolomites of the type MZr(BO3)2 (M = Ca, Sr, Ba) are reported. The Pb2+ ion is an efficient luminescent activator in these compounds. The Stokes shift is large. The Tb3+ ion is sensitized by Pb2+ (Rc ~ 9 Å). The Ti4+ ion shows at 300 K medium efficiency due to thermal quenching.
