Abstract

By comparing the results of calculations using the Mie theory, which is considered exact, a validity region of the approximate method for calculating the extinction cross section of spherical nanoparticles through polarizability has been found. The calculations were performed for w-CdS, InP, and PbS, and their results were presented in the form of the exact extinction cross section to the approximate absorption cross section ratio as a function of the particle size and light wavelength. The extinction coefficients for w-CdS and PbS nanoparticles depending on the wavelength and refractive index of the medium have also been calculated.

使用米氏理论和小尺寸近似法获得的 w-CdS、InP 和 PbS 纳米粒子消光截面的比较

摘要通过比较使用被认为是精确的米氏理论的计算结果，发现了通过偏振性计算球形纳米粒子消光截面的近似方法的有效区域。对 w-CdS、InP 和 PbS 进行了计算，计算结果以精确消光截面与近似吸收截面比的形式呈现，并作为粒度和光波长的函数。此外，还计算了 w-CdS 和 PbS 纳米粒子的消光系数与波长和介质折射率的关系。
