Shape oen has a decisive inuence over the properties and applications of monodisperse nanoparticles. In addition, size is another important factor controlling the properties of the nanomaterials owing to various connement effects. Therefore, the synthesis of diverse, high-quality nanoparticles with tunable shapes and sizes has become a challenging issue and drawn considerable attention. Morphology controllability has recently been realized through various approaches during the chemical synthesis of nanomaterials, especially for metal uorides. Metaluoride nanoparticles have a wide range of applications, from phosphors and uorescent host matrices to microelectronic/ optoelectronic devices and rechargeable batteries. Several chemical methods are generally employed to prepare metal-uoride nanoparticles, involving modied precipitation, microemulsion-mediated hydrothermal synthesis, the liquid–solidsolution (LSS) hydro-(solvo)thermal route, and co-thermolysis of multipleor single-source precursors in the presence of solvents. Among these approaches, precursor thermal decomposition and hydro(solvo)thermal methodology have attracted more attention. The thermal decomposition process usually involves dissolving organic precursors in high-boiling-point organic solvents with the
