The present invention is to provide a method for producing nanodiamonds doped with a Group 14 element, the method comprising: detonating by exploding an explosive composition containing at least one explosive and at least one Group 14 element compound in a sealed container to obtain nanodiamonds doped with at least one Group 14 element selected from the group consisting of Si, Ge, Sn, and Pb, and removing the Group 14 element and/or oxide thereof by subjecting the nanodiamonds doped with a Group 14 element to an alkali treatment.

Method for producing nanodiamonds doped with group 14 element, and method for purifying same

The present invention is to provide a heteroatom-doped nanodiamond, the heteroatom-doped nanodiamond being doped with at least one heteroatom, the heteroatom-doped nanodiamond satisfying criteria (i) and/or (ii) below: (i) a BET specific surface area being from 20 to 900 m/g, and (ii) an average size of primary particles being from 2 to 70 nm.
