Absorption of light by spherical nanoparticle

Click For Summary
SUMMARY

The absorption of light by spherical polystyrene nanoparticles scales with the diameter of the particle, specifically following the principles of Mie theory. In a vacuum, the absorption characteristics are influenced by the particle's size, with larger diameters leading to increased absorption cross-sections. The specific absorption remains constant for polystyrene, representing the proportion of light absorbed per unit area. For further understanding, refer to relevant literature on Mie scattering and nanoparticle optics.

Hello

Can anyone tell me how the absorption of a polystyrene nanoparticles scales as a function of its diameter.

The particle is spherical and it is placed in vacuum.

A reference to a paper I can read would be nice.

At this point I only want to know how the absorption scales not how much the particles absorbs.

Thanks.

The specific absorption would be a constant for the material (proportion of light absorbed per unit area).
What is the context?
 
I have this experiment where I can measure the absorption of light by a single nanoparticle. I would then like to calculate the detection limited based on the noise of the measurement and the signal induced by the particle I can detect.
