Abstract
The luminescence of the Pb2+ ion in the alkaline-earth fluorohalides w ith the PbFCl structure is reported. These systems show an ultraviolet emission at low temperatures, and a blue to yellowish emission at hig her temperatures. This is ascribed to the (co-) existence of two diffe rent excited states, one typical for Pb2+, and the other probably of c harge-transfer nature.
