I have an idea that would involve the measurement of an oscillating substance whilst the substance is immersed in a liquid. However, the method that I would use to measure the frequency of these oscillations is a novel one. Therefore, I need a benchmark.
Thus, can anyone direct me to a paper that gives the details - frequency, amplitude, characteristic size of the particles, etc. - of some kind of micron sized particle that will undergo oscillations when being excited by some kind of light source?
I've spoken to others in my department, and they have mentioned gold particles as such a benchmark. However, I have been unable to find a good paper detailing the types of vibrations I would need (i.e. the creation of longitudinal waves) under laser irradiation. Details on gold would, therefore, do the job nicely, but any such sized micron sized particle details would be great.
Spherical particles would be preferable given the geometry of my setup.
