Water-soluble infrared-to-visible fluorescent LaF(3) nanocrystals doped with different lanthanide ions (Er(3+)/Yb(3+), Eu(3+), Nd(3+), Tb(3+)) have been synthesized in methanol without using any ligands. These nanocrystals are easily dispersed in water, producing a transparent colloidal solution. The colloids of the Er(3+)/Yb(3+), Eu(3+), Nd(3+), Tb(3+) doped nanocrystals exhibit strong luminescence in the visible and near-infrared spectral regions.
在不使用任何配体的情况下，于甲醇中合成了掺杂不同镧系离子（铒离子/镱离子、铕离子、钕离子、铽离子）的水溶性红外到可见光荧光氟化镧纳米晶体。这些纳米晶体很容易分散在水中，形成透明的胶体溶液。铒离子/镱离子、铕离子、钕离子、铽离子掺杂的纳米晶体胶体在可见光和近红外光谱区域表现出强烈的发光。
