The luminescence properties of La/sub 3/TaO/sub 4/Cl/sub 6/ are reported and discussed. The rare earth ions Sm/sub 3/..mu.., Eu/sub 3/..mu.., Tb/sub 3/..mu.., Dy/sub 3/..mu.., and Tm/sub 3/..mu.. show characteristic absorption and emission lines. For Sm/sup 3 +/ and Eu/sup 3 +/, broad absorption bands are also observed and are attributed to charge-transfer transitions. The line emissions of Tb/sup 3 +/ are only from /sup 5/D/sub 4/, even at low (1 at.%) concentration. Broad excitation and emission bands were observed with In/sup 3 +/. These bands are attributed to In/sup 3 +/-Ta/sup 5 +/ ..-->.. In/sup 4 +/-Ta/sup 4 +/ charge-transfer transitions. An additional broad absorption at 250 and 280 nm leading to braod emission at 410 nm is ascribed to OH/sup -/ impurities.
