Abstract

The present invention discloses a hydrothermal synthesis method of LuO (OH) nanorods and Lu2O3 nanorods luminescent powder and relates to the rare earth nanometer material preparation and the microstructural regulation and control thereof. The method comprises the following steps: adopting commercial rare earth oxides (lutecium oxide and europium oxide) as raw materials, firstly dissolving the raw materials in concentrated nitric acid to prepared certain concentration lutecium nitrate doped with europium nitrate, then reacting with sodium hydroxide to prepare precipitate, then performing hydrothermal reaction in a sealed reaction tank at 160-200 DEG C to synthesize LuO(OH) nanorods; calcining LuO(OH) nanorods at 600-1000 DEG C for 1-3h and obtaining the corresponding Lu2O3 nanorods. The method process is simple and easily controllable and the feature of the product can be controlled within a certain concentration range of NaOH by adjusting the concentration of mineralizer NaOH in the hydrothermal process.

Description

technical field [0001] The present invention relates to a LuO(OH) nanorod and Lu 2 o 3 The invention discloses a method for synthesizing nanorod luminescent powder, which belongs to the technical field of preparation of rare earth luminescent materials. Background technique [0002] Due to the excellent properties of rare earth compounds in light-emitting devices, catalysis, medicine, biology, etc., a lot of research has been done on the synthesis and properties of rare earth compound materials. In recent years, the synthesis of nano-rare earth compounds with a certain aspect ratio has aroused great interest of material workers. At present, the methods adopted by people mainly include the following categories: 1. Hydrothermal method. For example, Li Yadong's research group at Tsinghua University reported a series of rare earth compounds Ln(OH) 3 , Ln 2 o 3 (Ln=Y, La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm) synthesis of nanorods and nanowires (Xun Wang and Yadong Li.
