Rc. Deboer et al., IDENTIFICATION OF GASEOUS OXYGEN AND NITROGEN IN BUBBLE INCLUSIONS INBI4(GEO4)3 (BGO) CRYSTALS BY MEANS OF RAMAN-SPECTROSCOPY, Journal of crystal growth, 140(3-4), 1994, pp. 361-364
Bubble inclusions in BGO crystals have been studied by means of Raman
spectroscopy. Since the crystals were grown under ambient atmospheric
conditions, we-focused our attention on oxygen and nitrogen. Both spec
ies are diatomic homonuclear molecules which are vibrationally and rot
ationally Raman active. Concerning the vibrational part of the 02 and
N2 Raman spectra, no evidence was found for the presence of both gases
. However, in the spectrum below the lowest 64 cm-1 energy mode of BGO
three faint peaks were found which show the characteristic features o
f the rotational spectra of O2 and N2. It was found that the compositi
on of the inclusion atmosphere was enriched by oxygen compared to the
composition of the air.
