Monodisperse lanthanide oxysulfide nanoplates and short nanorods were synthesized by the thermal decomposition of molecular precursors in the presence of oxygen. The nanoplates have uniform thicknesses and further self-organize to nanowires up to micron scale. The Eu2O2S and Eu3+-doped Gd2O2S nanocrystals both show unusual fluorescence properties obviously differing from the bulk powder phosphors, which are related to the surface-modification effects.
通过在氧气存在下热分解分子前驱体合成了单分散的硫氧化镧纳米片和短纳米棒。这些纳米片具有均匀的厚度，并进一步自组装成微米级的纳米线。Eu2O2S和Eu3+掺杂的Gd2O2S纳米晶体均表现出与块状粉末磷光体明显不同的异常荧光特性，这与表面改性效应有关。
