摘要

采用热蒸发法制备了薄膜形式的硫化铅(PbS)，以评价其光学特性。计算了光滑表面和粗糙表面条件下硫化铅在红外光谱3-11微米波段的吸收系数。计算和测量的吸收系数与塞米列托夫发表的结果吻合较好。这些结果比《固体光学常数手册》中发表的结果高出一个数量级。

Optical constants of lead sulfide in the 3-11 microns window

Lead sulfide (PbS) in thin film form was prepared by thermal evaporation in order to evaluate its optical characteristics. The absorption coefficient of lead sulfide in the 3-11 microns band of the infrared spectrum was calculated under smooth and rough surface conditions. The calculated and measured absorption coefficient was in a good agreement with that published by Semiletov. These results were an order of magnitude higher than that published in the handbook of optical constants of solids and referred to Scanlon.
