五磷酸铒(Erbium pentaphosphate)是一种稀土五磷酸盐LnP_5O_(14)(简称LnPP),它在光学尤其激光上有着重要的应用。早在七十年代初LnPP化合物就引起了人们普遍的重视。我们在完成了CePP等晶体结构的测定后,又测定了ErPP的晶体结构。
Erbium pentaphosphate is a rare earth pentaphosphate LnP_5O_ (14) (LnPP for short), which has important applications in optics, especially in lasers. As early as the early 1970s, LnPP compounds aroused widespread attention. After we finished the determination of the crystal structure of CePP, we determined the crystal structure of ErPP.
