“…5 (d)) was decomposed into seven components at 284.4, 285.2, 285.7, 286.8, 287.9, 289.7 and 292.8 eV. These peak values are attributed to C _ C, C-C, C _ N, C`N(C-O), C-N, CO bonded network and π-excitation respectively and are similar with other reports [29,40,41]. The spectrum showed that the peak intensity for sp 3 bonded carbon (C-C) has reduced significantly.…”

“…It indicates that the surfaces of Si-DLC films are rich in sp 2 bonded carbon. Another peak at 292.7 eV was attributed to π-excitation, which appears in all carbon compounds having double bonds [27][28][29]. The Si 2p spectrum was deconvoluted into five components with a strong peak for Si-C (Si 1+) bond at 100.7 eV and two small peaks for Si 2 O 3 (Si 3+) and SiO 2 (Si 4+) type of binding at 102.3 eV and 103.4 eV respectively (the number in bracket denotes the oxidation state of Si).…”

“…5 (g)) was deconvoluted into five components at 284.4, 285.1, 286.6, 288.5 and 293.5 eV. These peak positions are assigned to the binding energy of C _ C, C-C, C-O, C _ O bonded network and π-excitation respectively [25][26][27][28][29]45]. The ratio of the C _ C to C-C bonds was similar to that of the untreated Si-DLC film shown in Fig.…”

Surface energy and surface chemical bonds of the plasma treated Si incorporated diamond-like carbon films (Si-DLC) were investigated. The Si-DLC films were prepared by r.f. plasma assisted chemical vapor deposition using benzene and diluted silane (SiH 4 /H 2 = 10:90) as the precursor gases. The Si-DLC films were subjected to plasma treatment using various gases like N 2 , O 2 , H 2 and CF 4 . The plasma treated Si-DLC films showed a wide range of water contact angles from 13.4°to 92.1°. The surface energies of the plasma treated Si-DLC films revealed a high polar component for O 2 plasma treated Si-DLC films and a low polar component for CF 4 plasma treated Si-DLC films. The CF 4 plasma treated Si-DLC films indicated the minimum surface energy. X-ray photoelectron spectroscopy (XPS) revealed that the polarizability of the bonds present on the surface explains the hydrophilicity and hydrophobicity of the plasma treated Si-DLC films. We also suggest that the O 2 plasma treated surface can provide an excellent hemocompatible surface from the estimated interfacial energy between the plasma treated Si-DLC surface and human blood.

“…NC shows two distinct peaks at 400.9 eV and 398.9 eV. For HTMA-C, the peak at 399.8 eV corresponds to amine or cyano groups [38,50], while the smaller peak at 401.4 eV corresponds to quaternary nitrogen (N-Q) [22,25]. The significantly larger intensity of the peak at 399.8 eV suggests that most of the nitrogen found in this sample is in the form of surface funtionalities.…”

“…Although PTFE was also used to prepare these samples, the fluorine peak intensity is too low to separate from the background noise in the spectra. Each of the 3 samples exhibits a strong C1s peak near 284.8 eV, which is typical for pure carbon [49,50]. Detailed scans for O1s peak and N1s peak are shown in Fig.…”

In Situ Time‐Dependent and Progressive Oxidation of Reduced State Functionalities at the Nanoscale of Carbon Nanoparticles for Polarity‐Driven Multiscale Near‐Infrared Imaging

Surface abundant oxidize‐able functionalities at the nanoscale of carbon dots are prone to undergo sequential aerial oxidation leading to polarity‐driven wavelength tuning of their photoluminescence and consequently boost their quantum yields. With the progression of time, aerial oxidation is gradually increased from 1 to 6 h; consequently, a remarkable shift in the emission peak is observed, likely due to a gradual decrease in their respective band gaps leading to red shift of their photoluminescence. These bands are found to be dependent on the time of hydrothermal treatment of the model small molecules, i.e., benzophenone imine, and not on the size of the carbon core, as is the typical case for semiconductor quantum dots. Due to their high quantum yield (≈31%), it is demonstrated that these wavelength‐tuned carbon nanoparticles can be efficiently used for multiscale bioimaging, i.e., intracellular, deep tissue ex vivo and in vivo fluorescence bioimaging.
