Size tunable synthesis of solution processable diamond nanocrystals

Diamond nanocrystals were synthesized catalyst-free from nano-porous carbon at high pressure and high temperature (HPHT). The synthesized nanocrystals have tunable diameters between 50 and 200 nm. The nanocrystals are dispersible in organic solvents such as acetone and are isotropic in nature as seen by dynamic light scattering.
