Abstract

Erbium-doped ytterbium fluoride compounds with different crystal phases and morphologies have been synthesized via a facile hydrothermal route assisted with EDTA. Tunable upconversion emissions can be obtained by replacing Na⁺ with Li⁺ in NaYbF₄ microcrystals. An interesting blue shift is observed and a mechanism based on a weakened polarization effect is proposed.
