“…They have the smallest particle size among different kinds of synthetic diamonds, typically in the range of $10 nm, and exhibit outstanding mechanical, optical, electrical, and thermal properties [1]. This makes DNDs promising in a diversity of areas of science and technology, ranging from the 'conventional' applications such as abrasives, cutting and polishing tools [2,3], to the 'cutting-edge' ones -drug delivery, biomedical imaging, non-toxic contrast agents [4][5][6][7], magnetic sensors [8], composites [9,10], and quantum computing [11][12][13].…”

a b s t r a c tThe morphology and presence of impurities strongly influence mechanical, optical, electrical, and thermal properties of detonation nanodiamonds (DNDs). Here we report insights on the chemical composition and its effect on the optical properties of the DNDs obtained by rate-zonal density gradient ultracentrifugation. Herein, for the first time, a detailed valence band structure of as-prepared and oxidized DNDs is reported. Photoemission spectroscopy (PES) measurements demonstrate that the defects, originating from fullerene-like C bonding in the sp 2 shells of the DNDs, are governing the literature-reported loss of the emission spectral features arising from the nitrogen-vacancy (NV) center excitations. X-ray photoelectron spectroscopy (XPS) measurements reveal that nitrogen is present in the DNDs in the form of N-O bonded species located at the surface region/sp 2 shells, while in core of the DND it is in the form of N-C/N@C species.

“…[1][2][3][4][5][6] For example, diamond-like carbon can be deposited over large areas and at low substrate temperatures. 5 An important electronic property of such carbon based materials, which includes diamond, carbon nanotubes (CNT) and CNT-composites, is their ready ability to emit electrons into vacuum which make them suitable for applications in field emission display technology.…”

The origin of low threshold field emission (threshold field 1.25 V/μm) in nanocrystalline diamond-like carbon (nc-DLC) thin films is examined. The introduction of nitrogen and thermal annealing are both observed to change the threshold field and these changes are correlated with changes to the film microstructure. A range of different techniques including micro-Raman and infrared spectroscopy, X-ray diffraction, electron microscopy, energy dispersive X-ray analysis and time of flight-secondary ion mass spectroscopy are used to examine the properties of the films. A comparison of the field emission properties of nc-DLC films with atomically smooth amorphous DLC (a-DLC) films reveals that nc-DLC films have lower threshold fields. Our results show that nc-DLC can be a good candidate for large area field emission display panels and cold cathode emission devices.

“…[4][5][6] In addition, they can host photostable optically active defects, such as the nitrogen vacancy (NV) or the silicon vacancy (SiV) that have already been shown as effective bioimaging probes. [7][8][9][10] Moreover, single NV defects can be leveraged for high resolution magnetometry and sensing of single spins and individual biomolecules with unprecedented sensitivity.…”

Enhanced photoluminescence from single nitrogen-vacancy defects in nanodiamonds coated with phenol-ionic complexes

et al. 2015

Fluorescent nanodiamonds are attracting major attention in the field of bio-sensing and biolabeling. In this work we demonstrate a robust approach to surface functionalize individual nanodiamonds with metal-phenolic networks that enhance the photoluminescence from single nitrogen vacancy (NV) centers. We show that single NV centres in the coated nanodiamonds also exhibit shorter lifetimes, opening another channel for high resolution sensing. We propose that the nanodiamond encapsulation suppresses the non-radiative decay pathways of the NV color centers. Our results provide a versatile and assessable way to enhance photoluminescence from nanodiamond defects that can be used in a variety of sensing and imaging applications.
