Absorption of light by spherical nanoparticle

AI Thread Summary
The discussion focuses on how the absorption of light by spherical polystyrene nanoparticles scales with their diameter in a vacuum. The inquiry seeks to understand the scaling relationship rather than the specific absorption values. It is noted that the specific absorption remains constant for the material, indicating a consistent proportion of light absorbed per unit area. The context involves an experiment measuring light absorption by a single nanoparticle, with plans to calculate detection limits based on measurement noise and the signal from the particle. References to relevant papers on this topic are requested for further reading.

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.

Thread 'A quartet of epi-illumination methods'

Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...

Thread 'Effective absorption coefficient of gold nanoparticles'

I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
