Black phosphorus quantum dots (BPQDs) were synthesized using a liquid exfoliation method that combined probe sonication and bath sonication. When required, the black phosphorus can be converted back to red phosphorus, or even white phosphorus, for use in a semiconductor or other process. Phosphorus also plays a role in the making of steel. That crystal structure, Atwater says, makes the black phosphorus have significantly anisotropic optical properties. The energies inaccessible to electrons in black phosphorus and arsenic are different. Graphite is a form of carbon used in "lead" pencils. The outer shell arrangement therefore resembles that of nitrogen, with three half-filled orbitals each capable of forming a single covalent bond and an additional lone-pair of electrons.
