Abstract
Heavily Cu+ -doped amorphous PbCl2 has been obtained by quench deposition of the mixture of PbCl2 and CuCl. Upon crystallization, the large majority of Cu+ ions aggregate to form CuCl precipitates embedded in the crystalline PbCl2 matrix. The present experiment opens up the possibility of producing densely dispersed CuCl clusters in a controlled manner in PbCl2 films.
