摘要：A molten salt route to LaF3:Eu3+ nanoplate with tunable size was developed and the products were characterized by the X-ray diffraction (XRD), transmission electron microscopy (TEM), field-emission scanning electron microscopy (FE-SEM) and high-resolution TEM (HR-TEM). It is found that the nanoplates with different sizes (ca. 46, 20, and 12 nm) could be obtained when the molar ratio of the reagents NH4F and La(NO3)(3) center dot 6H(2)O was adjusted. The possible formation process of reaction was discussed, and the reasonable mechanism of size controlling was also proposed. Furthermore, the luminescent properties of all the samples with different sizes and doping levels were investigated at room temperature.
