K2O-B2O3-Al2O3 유리계의 IR 스펙트럼에 대한 기구 연구

다국어 초록 (Multilingual Abstract)

The ternary glasses in the system K2O-B2O3-Al2O3 were fabricated in the ratio of
R(=K2O mole% / B2O3 mole%) and K(=Al2O3 mole% / B2O3 mole%). The infrared
absorption spectra of these glasses were measured within the scope of the wavenumber
400cm-1∼2000cm-1 using IR spectrometer. The infrared absorption spectra were analyzed
how the intensity and position of the peck become different as a function of R and K,
so the mechanism of a spectra pecks was identified.
For example, the peaks of the spectra within the band of the wavenumber
440-480cm-1 are an absorption of Al-O-B(BO4
-structure) bending vibration, and the
peaks within 570-600cm-1 are an absorption of Al-O-B(BO3 structure) bending
vibration. The peaks within 700-750cm-1 are an absorption of B-O-B bending vibration
between BO3 structure and BO4
- structure, and the peaks within 765-775cm-1 are an
absorption of B-O-B bending vibration between two BO3 structures.
In the same way, the absorption peaks within the band of the wavenumber
900-960cm-1, 840-860cm-1, 1040-1060cm-1
, 1200-1230cm-1

, 1270-1320cm-1
,
1360-1400cm-1
, 1646-1648cm-1 and 1737-1747cm-1 are analyzed into detail according to
an atomic bonding of the structures of glass. The detail contents are explained in the
