| 中文摘要 | water-soluble ln(3+)-doped beta-nagdf4 (ln = ce, tb, eu, dy) nanocrystals were synthesized via a hydrothermal method followed by phase transferring. the nanocrystals crystallize in the hexagonal phase as beta-nagdf4. tunable multicolor down-conversion emissions can be achieved from ln(3+)-doped beta-nagdf4 nanocrystals under a single ultraviolet excitation. during the down-conversion emission, energy transfer process like ce3+ -> gd3+ -> (gd3+)(n) -> ln(3+) occurred, in which gd3+ ions play an important intermediate role. the magnetic properties of the obtained nanocrystals were investigated in detail. the nanocrystals display paramagnetic and superparamagnetic properties with mass magnetic susceptibility values of 6.77 x 10(-5) emu/g . oe and 1.92 x 10(-3) emu/g . oe at 300 k and 2 k, respectively. the t-1-weighted magnetic resonance image that measured in aqueous solutions with different gd3+ concentrations reveals the contrast brightening increases with the concentration of gd3+ ions. such magnetic/luminescent dual-function material may have promising applications in multiple biolabels and magnetic resonance imaging.
