摘      要：Nanodiamonds have outstanding mechanical properties,chemical inertness,and biocompatibility,which give them potential in various *** methods for preparing nanodiamonds often lead to products with impurities and uneven *** report a two-step high-pressure high-temperature(HPHT) method to synthesize nanodiamonds using naphthalene as the precursor without metal *** grain size of the diamonds decreases with increasing carbonization time(at constant pressure and temperature of 11.5 GPa and 700℃,respectively).This is discussed in terms of the different crystallinities of the carbon *** probability of secondary anvil cracking during the HPHT process is also *** results indicate that the two-step method is efficient for synthesizing nanodiamonds,and that it is applicable to other organic precursors.
