摘要

The emission and excitation spectra of Ce~(3+) and Pr~(3+) doped into the cubic host Cs_2NaYF_6 have been recorded at room temperature and ～10 K using synchrotron radiation. The two 5d ~1 T_(2g) states of Ce~(3+) have been located from the excitation spectra, whereas the Eg state is placed above the host band gap. Decay measurements of the 5d~(1 →)4f~1 Ce ~(3+) emission, and spectra collected using selective excitation, indicate the occupation of more than one type of site by Ce~(3+) in this host lattice. By contrast, the location of features in the 4f ~15d~(1 →) 4f~2 emission of Pr~(3+) is independent of the excitation wavelength. Assignments are presented for some of the 4f~15d~1 levels and for the Pr~(3+)-F ~- charge transfer band. The 5d emission lifetimes for Ce~(3+) and Pr~(3+) in the Cs_2NaYF_6 host are 42 and 29 ± 1 ns, respectively, and are not temperature-dependent.
