摘要

Nanodiamond (ND) photoluminescence (PL) can increase by up to 247 times with 488 nm excitation when enolates from the decomposition of tetrahydrofuran form an anionic organic shell and the deprotonation of the protons on the ND surface induces band bending in the presence of bulky, non-nucleophilic bases like lithium bis(trimethylsilyl)amide.
