在稀土五磷酸盐中稀土离子不仅组成化学当量比的化合物,而且每个稀土离子都处于完全隔离的笼状结构之中。我们发现五磷酸铽(TbP_5O_(14)晶体能发出较强荧光,这种性质将有可能使TbP_5O_(14)成为一种有
In rare earth pentaphosphates, rare earth ions not only form stoichiometric compounds, but also each rare earth ion is in a completely isolated cage structure. We found that terbium pentaborate (TbP_5O_ (14) crystal emits more fluorescence, and this property will make it possible to make TbP_5O_ (14) a
