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.
