Abstract
Boron-doped amorphous carbon powders were produced at 1000 °C and under one atmosphere of pressure using a simple tube furnace. Doping was monitored using XRD and Raman spectroscopy, and boron content was confirmed by XPS. The XPS data showed a peak at 188 eV which coincides with the B1s energy when bound to carbon. XRD data showed a decreasing d002-spacing, indicating increased graphitization upon doping. The full width at half maximum of this peak decreased, probably due to an increase in grain size upon boron doping. Raman spectroscopy showed a decrease in the height of the G-band, due to the boron substitution. The intensity ratio of the G- to D-bands increased, indicating larger grain sizes in the powders.
