Abstract

Solid-state nuclear magnetic resonance (NMR) spectroscopy is used to study heavily Yb ³⁺ and Er ³⁺ doped, fluorescent NaY _1-x-y Yb _x Er _y F ₄ nanoparticles. An understanding of the ¹⁹ F wide line NMR response suggests that the 0 ppm portion of the ¹⁹ F NMR spectrum can be used as a probe of trivalent lanthanide content via spin-lattice relaxation time changes. A Yb ³⁺ and Er ³⁺ magnetic interaction is manifest as a cooperative contribution to the ¹⁹ F spin-lattice relaxation rate in heavily co-doped nanoparticle samples. The results from this study will aid in the understanding of the mechanism of enhanced optical up-conversion among these well-known nanostructures.
