The luminescence properties of Eu/sup 2 +/, Sn/sup 2 +/, and Pb/sup 2 +/ in SrB/sub 6/O/sub 10/ have been studied both at roomtemperature and liquid-helium temperature and the decay times of Sn/sup 2 +/ and Pb/sup 2 +/ in this matri have been measured and analyzed. According to the emission spectrum of Eu/sup 2 +/ there seems to be three different cation sites in SrB/sub 6/O/sub 10/. Europium, tin, and lead were also used as sensitizers for Mn/sup 2 +/ and the energy transfer processes were characterized. Eu/sup 2 +/-Mn/sup 2 +/ energy transfer was inefficient due to the transfer within different Eu/sup 2 +/ centers. The sensitization action of Sn/sup 2 +/ and Pb/sup 2 +/ on Mn/sup 2 +/ was different because lead-lead energy transfer occurs (even at 4.2 K) but tin-tin transfer can be neglected. A fast diffusion model for the Pb/sup 2 +/ system is suggested.
