Synthesis and spectroscopic analysis of Ce3+ and Gd3+-doped NaYF4: UV-emitting phosphors prepared by solid-state metathesis
A new method of synthesis for NaYF4 is reported. The method involves highly exothermic solid-state metathesis reaction between metal chlorides and NaF. The synthesis is very fast and the metathesis reaction is over within several minutes. Initiation of the reaction is marked by the appearance of the flame and the completion by its extinguishing. The product was characterised by various techniques like X-ray diffraction, electron microscopy, energy dispersive spectroscopy and elemental mapping. Mixed α and β phases were formed with cubic and hexagonal structures, respectively. Ce3+- and Gd3+-activated NaYF4 phosphors were successfully synthesised by this method as could be judged from the typical emission and excitation spectra. Solid-state metathesis thus provides a tool for fast, simple synthesis of this important class of phosphors.
期刊介绍：
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
