AbstractWater-soluble hexagonal NaScF4:Yb/Er upconversion microcrystals (UCMCs) were synthesized using the hydrothermal method. The upconversion photoluminescence properties of NaScF4:xYb/2%Er microcrystals (x=4-20%) were characterized under a 980-nm-wavelength laser excitation. The dependence of red/green (R/G) ratio on the concentration of Yb3+ ions was investigated. The local environments of dopant ions (Yb3+, Er3+) in NaScF4 were studied using multiple solid-state nuclear magnetic resonance (NMR) techniques. The F-19 single pulse and F-19{Na-23} and F-19{Sc-45} rotational echo double resonance (REDOR) techniques proved that the dopant rare-earth ions (Yb3+, Er3+) preferred to substitute Na+ rather than Sc3+ ions. Such solid-state NMR techniques provide a novel approach to study new phosphors. (C) 2017 Elsevier B.V. All rights reserved.
