摘要: Highly complex luminescence behavior is exhibited by single crystals of SrCl2:Yb+2 when excited near-ultraviolet radiation. The photoluminescence characteristics the system were established on basis decay-time measurements and studies temperature dependence emission intensities. Two five bands observed at low temperatures are assigned to 4f14←4f135d transitions Yb+2 ion. centers responsible for other three have not yet been identified, but they appear involve ytterbium in some form. One these corresponds well-known green CaF2:Yb+2, due a transition from level configuration Yb+2, as has suggested.
