BaF 2 fled no more : Monodisperse cubic‐ and orthorhombic‐phase BaF 2 nanocrystals were formed readily by the liquid–solid–solution approach. Nucleus growth of BaF 2 occurs under kinetic control, whereby their size and morphology depend greatly on the ripening time and concentration of surfactants (see scheme). The phase of the BaF 2 crystals is under thermodynamic control.
