Abstract

2.5~40$mu extrm{m}$ 영역에서 $XAs_2S_3-(1-X)GeS_2$ 유리의 적외선 흡수에 관하여 연구했다/ Lucovsky와 그의 연구팀이 제창한 ""분자모델""에 의하면 $8-20\mu\textrm{m}$ 영역에서 위의 유리물질의 multiphonon 흡수대는 고립된 각 분자의 기본진동대의 overtone 및 combination 과 같다. 그러므로 multiphonon 흡수영역에서 AsY3 와 GeY3의 기본진동수를 모두 가지고 있는 combination 대는 관찰되지 않고 또한 혼합된 $XAs_2S_3-(1-X)GeS_2$ 유리의 흡수계수는 순수한 $As_2Y_3$ 및 $GeY_2$ 유리의 흡수계수를 더한 것으로 표현된다. 실험에서 얻은 흡수계수는 이 분자모델로부터 예상되는 값과 잘 일치한다.값과 잘 일치한다.
