Abstract
Abstract Monodisperse Gd4O3F6 spindle-like microcrystals have been successfully synthesized via a hydrothermal process followed by heat treatment by using 1-octyl-3-methylimidazolium tetrafluoroborate ([Omim]BF4) as fluorine source and morphology controller. The possible formation mechanism of the spindle-like microcrystals has been proposed based on the time-dependent experiments. The down- and up-conversion (DC and UC) luminescence properties of Gd4O3F6:Ln3+ (Ln = Eu, Tb, Dy, Ho, Tm, Sm, Yb/Er, Yb/Ho) samples are studied and the energy transfer mechanism between Dy3+-Eu3+, Yb3+-Er3+ and Yb3+-Ho3+ were further discussed. In addition, down- and up-conversion multicolor luminescence of Dy3+-Eu3+ or Yb3+-Er3+ co-doped Gd4O3F6 phosphors have been successful realized by changing the concentrations of Eu3+ and Yb3+ ions, which demonstrate that Gd4O3F6 crystal is a potential luminescent host for phosphors.
