中文摘要 | 鈣鋁鍺玻璃其波其從近紫外光區(0.2μm)到中紅外光區(5-6μm)展現出高的透明度,它是一種高紅外穿透的材料,在這一篇論文中用紅外光譜的技術來研究兩種鈣鋁鍺玻璃被水侵蝕後的表面層,從這些玻璃的紅外吸收光譜的量測可得到時間與溫度的涵數的關係,而吸收係數和浸泡時間的兩者之間的關係可由一般的擴散理論及這些玻璃表面層逐漸產生的吸收峰有關連。 |
英文摘要 | Calcium aluminogermanate glasses exhibit high transparency over frequencies ranging from the near UV (0.2 μm) to the mid-IR (5∼6μm). They are excellent infrared transmitting materials. In this paper the attack of pure water on the surface layer of two calcium aluminogermanate glasses was studied by IR spectroscopy. Infrared absorption measurements were performed as a function of time and temperature for these glasses. The relationship between the absorbance and immersion time will be discussed in light of diffusion theory and the development of the absorption peak is related to a surface layer formation on these glasses. |
