Abstract

The invention provides a method for preparing rare earth ion europium-doped sodium gadolinium tetrafluoride (NaGdF4:Eu3+) luminescent nanorods and a method thereof, belonging to the technical field of preparation of rare earth doped luminescent materials. The present invention comprises the following steps: (1) mixing compound rare earth ions and sodium lauryl sulfate in proportion, and then adding fluoride to form a mixed solution; (2) carrying out hydrothermal reaction on the mixed solution at a certain temperature and time, Obtain the NaGdF4:Eu3+luminescent nanorods. The method has a simple synthesis process and is easy to produce in batches, and the prepared NaGdF4:Eu3+ nanorods have good red luminescent properties. The invention uses rare earth metal oxides as raw materials and sodium lauryl sulfate as a surfactant, and the whole reaction is carried out in an aqueous solution without any organic solvent, which is economical and environmentally friendly, has strong practicability, and has wide application prospects.

Description

technical field [0001] The invention relates to a rare earth europium ion doped sodium gadolinium tetrafluoride (NaGdF 4 :Eu 3+ ) The method for preparing nanorods belongs to the technical field of preparation of rare earth doped luminescent materials. Background technique [0002] Rare earth-doped luminescent material is an important luminescent material in the family of inorganic luminescent materials. It is widely used in display lighting, lasers, optical fiber amplifiers, anti-counterfeiting technology and bioluminescent marking. NaYF 4 and NaGdF 4 The representative rare earth tetrafluoride is a kind of fluoride host material with low phonon energy, and the degree of rare earth ion excited state quenching is small, and has high thermal and environmental stability. Therefore, nano-luminescent materials based on tetrafluoride research has attracted great attention. [0003] NaGdF 4 :Eu 3+ It is a very important fluoride red luminescent material, and its preparation...
