Low temperature synthesis of boron phosphide nanocrystals

Nanocrystalline boron phosphide (BP) was successfully synthesized at low temperature (400 °C) by a simple reaction between PCl 3 and NaBF 4 using Na as reductant. X-ray powder diffraction patterns indicated that the resultant was cubic BP with a lattice constant a=4.533 Å. Transmission electron micr...

Description
Summary:Nanocrystalline boron phosphide (BP) was successfully synthesized at low temperature (400 °C) by a simple reaction between PCl 3 and NaBF 4 using Na as reductant. X-ray powder diffraction patterns indicated that the resultant was cubic BP with a lattice constant a=4.533 Å. Transmission electron microscopy revealed that the crystals were composed of spherical particles with the diameter of 80 nm or so and lots of worm-like rods. The possible formation mechanism was also investigated.
