CaF2 nanocrystals with a clear cubic shape were synthesized using both simple mixing and a hydrothermal method that neither of which required the use of surfactants or dispersants. The concentration and pH of the reaction medium, which in this case was an aqueous HNO3 solution, was found to be very important for determining the morphology of the CaF2 particles.
