Abstract

The present invention relates to a fluorescent nanodiamond preparing method including a first operation of preparing nanodiamonds having an average particle diameter of 10 nm or less, a second operation of implanting plasma ions into the nanodiamonds, a third operation of heat-treating the nanodiamonds implanted with the plasma ions under a vacuum or inert gas atmosphere, a fourth operation of oxygen treatment of the heat-treated nanodiamonds under a gas atmosphere including oxygen to oxidize the surfaces of the nanodiamonds, a fifth operation of acid-treating the oxygen-treated nanodiamonds, a sixth operation of centrifuging and cleaning the acid-treated nanodiamonds, and a seventh operation of drying the cleaned nanodiamonds, wherein, in the second operation, the plasma ions are implanted at an incident ion dose of 10ions/cmor more and 10ions/cmor less.
