Abstract

Single crystals of the mixed anion rare earth sulfate fluorides LnSO₄F·H₂O (Ln = Nd, Tb, Dy, and Ho), monoclinic space group P2₁/n, were prepared via an HF-free mild hydrothermal synthesis. Furthermore, the LnSO₄F·H₂O (Ln = Nd, Tb, Dy, and Ho) phases, orthorhombic space group Pnma, were obtained via the thermal decomposition of LnSO₄F·H₂O (Ln = Nd, Tb, Dy, and Ho). While the LnSO₄F·H₂O (Ln = Nd, Tb, Dy, and Ho) phases are isostructural, two different structures are observed for the LnSO₄F (Ln = Tb, Dy, and Ho) series, one for Tb and one for Dy and Ho, differing in the rare earth coordination environments. Green photoluminescence is observed for Tb(SO₄)F·H₂O and Tb(SO₄)F. Magnetic measurements indicate the absence of magnetic order down to 2 K in the Ln(SO₄)F·H₂O and Ln(SO₄)F phases.
