摘要：

Crystals of the scheelite structure fluoride LiYF4 have been grown doped with 0.24, 1.4 and 2.2 at. per cent Nd3+. The polarized fluorescence and absorption, excitation spectra, lifetime decay and linewidths have been measured at 77° and 300°K. The optical data of LiYF4: Nd3+ have been compared with data on the isomorphous oxide CaWO4: Nd3+. The spectroscopic features of LiYF4:Nd3+ are: a long lifetime of 500 μsec which decreases rapidly with increasing Nd-concentration; a narrow linewidth of 2 cm-1 at 77°K; and a high absorption in the near infrared. These factors have been related to its potential as a laser material. © 1969.
