Matrix-inducing synthesis and luminescence of Zn2SiO4:xTb3+ submicrometer phosphors derived from the sol–gel assembling of different multicomponent hybrid precursors

Characterization of rare-earth doped Lu2O3 nanopowders prepared with polymer complex solution synthesis

“…5b). In this case the characteristic emission of Tb 3+ was distributed into four groups, corresponding to the following f-f transitions 5 D 4 → 7 F 6 (483.5, 488.5, 492, 497.5, 502.5 nm), 5 D 4 → 7 F 5 (542, 548, 550.5, 552, 554 nm), 5 D 4 → 7 F 4 (578.5, 580, 583, 585, 588.5, 590.5, 593, 598, 595.5, 600 nm), 5 D 4 → 7 F 3 (615, 621.5, 624, 627.5, 629.5 nm) [20]. Their barycenters were found, respectively, at 490.71 nm (blue), 547.16 nm (green), 589.31 nm (orange) and 622.45 nm (red).…”
