| 中文摘要 | uniform and dispersive lu2o3:yb3+/er3+/tm3+ nanocubes have been successfully synthesized by hydrothermal process with subsequent calcination at 900 degrees c. the as-formed re3+-doped lutetium oxide precursor via the hydrothermal process, as a template, could transform to re3+-doped lu2o3 with their original cubic morphology and slight shrinkage in the size after post-annealing process. the formation mechanism for the lutetium oxide precursor cubes has been proposed. under single wavelength diode laser excitation of 980 nm, the as-obtained lu2o3:3%yb3+/0.5%er3+/03%tm3+ nanocubes show nearly equal intensities of blue (tm3+: (1)g(4) -> h-3(6)), green (er3+: (h-2(11/2), s-4(3/2)) -> i-4(15/2)), and red (er3+: f-4(9/2) -> i-4(15/2)) emissions, which produces bright white light emission, clearly visible to the naked eyes. the main pathways to populate the upper emitting states come from the energy-transfer processes from yb3+ to tm3+/er3+, respectively. the chromaticity coordinate of the lu2o3:3%yb3+/0.5%er3+/0.3%tm3+ sample is calculated to be about x = 0.3403 and y = 03169, which falls exactly within the white region of 1931 cie diagram and is very close to the standard equal energy white light illuminate (x = 0.33 and y = 0.33), pointing out its potential use as a white light source under 980 nm laser diode excitation.
