采用熔盐法成功合成了Lu 2 Ti 2 O 7纳米片。所制备的Lu 2 Ti 2 O 7纳米片实际上由具有典型立方萤石结构的单晶组成。所制备的Lu 2 Ti 2 O 7纳米片的直径范围为500-1000 nm，厚度可达数十纳米。其可能的生长机制为“形状记忆效应”，但由于Lu_2O_3取代Lu（NO_3）_3，这种效应明显减弱。最后，我们系统地研究了不同形貌的Lu 2 Ti 2 O 7纳米颗粒的光致发光特性。
Lu2Ti2O7 nano-plates are successfully synthesized via a molten salt technique and first reported in this paper. The as-prepared Lu2Ti2O7 nano-plates are actually composed of single crystals with a typical cubic fluorite structure. The diameters of the fabricated Lu2Ti2O7 nano-plates range from 500–1000 nm with thicknesses up to several tens of nano-meters. The possible growth mechanism is suggested as ‘shape memory effect’, which is weakened significantly by the substitution Lu2O3 for Lu(NO3)3. Finally, we systematically investigate the photoluminescence properties of Lu2Ti2O7 nano-particles with various morphologies.
