| Summary: | Natural and synthetic beryl, Al2
Be3Si
6O18, from various deposits and manufacturers
were investigated with Raman, I R spectroscopy, Laser Ablat ion I nductivel y Coupled Pl asma Mass
Spectrometr y (LA-I CP-MS) and Electron Microprobe Analysis (EMPA). The Raman-band at
1067-1072 cm
-1
and the IR-band at 1071-1207 cm
-1
have been assi gned till now either to Si-O or
to Be-O by di fferent studies. Following the findings in this study that the position and Full Width
at HalfMaximum (FWHM) of these bands were related to the concentration of silicon but not that
of beryllium, it stated that these bands were generated by the vibration ofSi-O. |
