Description
Summary:Regular CaF2:Eu3+ nano-cubes undergo ionic liquid mediated synthesis reactions in the presence of Eu(NO3)3⋅6H2O. The formation of monodisperse cubic crystallites relies primarily on a one-pot hydrothermal method. [Display omitted] •Ionic liquid plays as double roles: reagent and direction template.•Controllable morphologies were achieved.•Photophysical properties were extensively studied. Regular CaF2:Eu3+ nano-cubes undergo ionic liquid (diallyldimethylammonium tetrafluoroborate, abbreviated as DTB)-mediated synthesis reactions in the presence of Eu(NO3)3⋅6H2O. The formation of uniform and mono-dispersed particles relies primarily on a one-pot hydrothermal method. The correlations between reaction temperature, doping concentration and crystalline structures have been clarified. In addition, the photoluminescence features and their influencing factors were extensively studied. In the case of Eu3+ containing phosphors, the application of new structure directing reagents will be convenient for the design of functional nanomaterials.
