The luminescence of La/sub 3/NbO/sub 4/Cl/sub 6/ with trigonal bipyramidal NbO/sup 5 -//sub 5/ groups is reported. The Nb/sup 5 +/ coordination does not seem to influence the niobate emission. The luminescence and Raman spectrum of La/sub 3/TaO/sub 4/Cl/sub 6/ are also reported. Finally, differences in luminescence of the M and M' modifications of YTaO/sub 4/ are discussed.
