dc.description.abstract |
Despite hot pressing being the most popular method of consolidating B6O powder, the Raman spectrum of polycrystalline hot-pressed B6O was until now poorly understood. Yet, recent reports have contributed to the understanding of only high-pressure and high-temperature sintered B6O. Using an automated method for subtraction of the fluorescence background from Raman measurements, the first- and second-order Raman spectra of B6O and their dependence on the wavelength of the excitation line from a green Argon ion (Ar+) laser are reported. The authors' results confirm the existence of observable highly resolved first- and second-order Raman modes measured at ambient conditions using a green Ar+ ion laser as the source of excitation. They also extend their study to present a comparative analysis of their recovered first-order Raman spectra and previously reported first-order Raman spectra other a-rhombohedral boron type based ultra-hard boron-rich ceramic materials. The results show an overall good agreement. |
