Synthesis of Cerium Tetrafluoride and Cerium Trifluoride Nanoscale Polycrystals from Ammonium Hydrogen Difluoride.

This paper reported a dry synthesis and characterization of cerium tetrafluoride (CeF) and cerium trifluoride (CeF) nanoscale polycrystals (NPs). The CeF NPs were spherical or flaky and approximately 10 ± 2 nm in diameter. The CeF NPs were rod-shaped nanorods with a length of about 150 ± 5 nm and a diameter of about 20 ± 2 nm.
