Abstract
A method of making molecularly doped nanodiamond. A versatile method for doping diamond by adding dopants into a carbon precursor and producing diamond at high pressure, high temperature conditions. Molecularly doped nanodiamonds that have direct incorporation of dopants and therefore without the need for ion implantation. Molecularly-doped diamonds that have fewer lattice defects than those made with ion implantation.

A molecularly doped nanodiamond made from the steps comprising:
- adding a dopant to a sol-gel precursor;
- synthesizing via sol-gel synthesis an amorphous carbon aerogel comprising an open pore network;
- drying the amorphous carbon aerogel;
- sintering the amorphous carbon aerogel;
- preserving the open pore network;
- loading the amorphous carbon aerogel into a diamond anvil cell;
- forming a sealed chamber around the amorphous carbon aerogel;
- flowing a noble gas into the sealed chamber;
- liquefying the noble gas by condensation;
- allowing the liquefied noble gas to fill the open pore network of the doped amorphous carbon aerogel;
- generating noble gas defects within the doped amorphous carbon aerogel;
- without using ion implantation;
- pressurizing the diamond anvil cell;
- heating the doped amorphous carbon aerogel incorporating the noble gas dopants;
- and
- transforming the doped amorphous carbon aerogel incorporating the noble gas dopants into molecularly doped nanodiamond incorporating the noble gas dopants.
A molecularly doped nanodiamond comprising:
- an amorphous carbon aerogel comprising noble gas defects within the amorphous carbon aerogel,
- wherein the amorphous carbon aerogel was formed via sol-gel synthesis and
- wherein the amorphous carbon aerogel comprises an open pore network and
- wherein the amorphous carbon aerogel was loaded into a diamond anvil cell, was subjected to a noble gas that was liquefied and filled the open pore network, and
- wherein without using ion implantation the amorphous carbon aerogel was doped with noble gas and the doped amorphous carbon aerogel incorporated the noble gas dopants therefore resulting in molecularly doped nanodiamond incorporating the noble gas dopants.
