“…10,11 Based on the research previously made by the present authors, Na was efficiently intercalated into B/C/N material which was prepared at 1770 K. According to this information, B/C/N materials prepared at 1770 K having two different compositions were used in this study. The B/C/N thick film was prepared at 1770 K using boron trichloride ( /min) as the starting materials under atmospheric pressure.…”

Graphite-like layered materials composed of boron/carbon/nitrogen (B/C/N) and boron/carbon (B/C) have been prepared by CVD method using BCl 3 and CH 3 CN or C 2 H 4 as starting materials, respectively. Electrochemical behaviors of B/C/N and B/C materials as anodes of sodium ion batteries have been investigated. Their properties have been compared with those of carbon/nitrogen (C/N) material and carbons prepared by CVD method. B/C/N and B/C materials showed reversible intercalation and de-intercalation on their discharge and charge cycles. The formation of stage structures was observed during the discharge (electrochemical intercalation) in 1 M-NaPF 6 / EC+DEC (1:1) electrolyte solution, which was not clearly observed in the cases of C/N material and carbon. Potentials at the beginning of discharge (intercalation of Na + ion) were higher than those of C/N material and carbons, and depended on the boron content in the material. B/C materials having larger boron content tended to show higher reversible capacity. B/C/N materials showed highest reversible capacity 190 mAh g −1 among the materials prepared in this study by using CVD method. These results could be explained by the electronic structure of the material in which electron deficient boron atom lowered the bottom of conduction band, and will provide useful information for designing materials as electrodes.

“…Since one BN molecule is isoelectronic with two carbon atoms and h-BN has the same layered structure as graphite carbon, it is expected that the atomic level hybridization of h-BN and graphite produces a new semiconducting compound BNCx with a tunable band gap energy depending on its composition (x) and the atomic configuration in the layer [11][12][13]. To date, BNCx compounds, in particular onedimensional nanostructures, with x from 0 to 7 have been prepared by various methods and their photoluminescence (PL) properties have been investigated [14][15][16][17][18][19].…”

BCNO phosphor derived from a low-temperature urea route is an efficient and environmental-friendly phosphor with emission covering the full visible and the near ultraviolet region. Systematic characterization of the BCNO phosphor was carried out by means of steady state and time-resolved spectroscopy in order to unveil the origins of different luminescence centres. Two emission bands located at 335 and 410 nm together with a changeable band located ranging from 380 to 580 nm are identified and related to the presence of carbon defects as inferred from electron paramagnetic resonance spectroscopy. The emission of the changeable band exhibits a long persistent character, which depends on the emission energy of the specimens and originates from the tunnelling recombination of electrons with the emission centres. The spectroscopic properties of the BCNO phosphor are discussed in detail and a configurational coordinate model is constructed for the explanation of the photoluminescence as well as the afterglow behaviour.

“…There has been some success in preparing B x C y N z compositions. [1][2][3] The subject has become of great interest recently because of the relevance of such materials to graphene, which is a two-dimensional network of sp 2 -hybridised carbon atoms. 4,5 Some investigations on compositions formed between boron and carbon as well as carbon and nitrogen are only recently have received attention.…”

High carbon-rich boroncarbonitride thin films have been grown by pulsed laser deposition (PLD) technique with using BN-C dual-targets. Fourier-transform infrared (FTIR) spectroscopy results presented B-N, B-C and C-N bonds, indicating the as-deposited thin films were new ternary compounds. B-N, B-C and C-N bonding structures were also detected by X-ray photoelectron spectroscopy (XPS), and carbon content fell into a large range of 45.8 to 85.9%. The films exhibited good thermalstability in vacuum, whereas were oxidized at 600 oC in air.
