1. A cutting element for an earth-boring tool, comprising:
a substrate; and
a polycrystalline diamond material directly attached to the substrate, the polycrystalline diamond material comprising:
grains of diamond material;
diamond nanoparticles bonded to the grains of diamond material; and
a material disposed within and approximately filling all interstitial spaces between the grains of diamond material and the diamond nanoparticles, the material consisting of aluminum fluoride;
wherein the polycrystalline diamond material is substantially free of a metal-solvent catalyst.
