Abstract:

Hexagonal sodium yttrium fluoride has been successfully synthesized via a facile solvothermal route, using yttrium nitrate, sodium fluoride and polyethanediol as raw materials to react in propanetriol solvent. The as-prepared product was characterized by powder X-ray diffraction, scanning electron microscopy, thermogravimetric and differential thermal analysis, Fourier transform infrared spectrum and energy dispersive X-ray spectrum. The characterization results revealed that the products are hexagonal and denoted as NaYF4. The as-synthesized hexagonal sodium yttrium fluoride composed of hollow-structured nanotubes self-assembled and arrayed orientedly to take on bamboo raft morphology. Hexagonal NaYF4 nanotube arrays exhibited high heat stability. This study provides a simple method to prepare bamboo raft-shaped NaYF4 in large scale, which broads their practical applications.
