✦ Synopsis

The luminescence properties of Bi4Ge3012 (BGO)-related compounds are reported. Pb4(PO4)2SO 4 shows a similar emission to BGO which is ascribed to an activator-perturbed exciton state or the so-called D-level. Compositions diluted with noble gas cations as well as Pb3Bi(PO4) 3 show luminescence of s2~ sp type on the s 2 ion. A search for new scintillator candidates did not appear to be successful but yielded insight into the luminescence of these compounds.
