Histogram of CaF2 nanoparticle size distribution, obtained via measuring the sizes of 200 particles on TEM pictures. The particle size ranged from 15 nm to 335 nm, with a median (50th percentile) of 56 nm. BET surface area measurement yielded a specific surface area of 35.5 m2/g, and a calculated CaF2 particle diameter of 53 nm.
