Effect of physical parameters on the self-oscillation frequency (νs, Equation (4))—its value lowers with larger nanoparticle mass (m) and thermal conductivity of the dispersant (kT), and rises with increasing light–matter interaction (absorption cross-sectionσ, light power densityI). The larger the heat capacity ratio (nanoparticle to dispersant,γ=cn/cs), the smaller the frequency. As the nanoparticle thermal inertia increases relative to the inertia of the environment (a largerγ), vibrations get mechanically softer/slower (vice versa, they get stiffer/faster if the thermal inertia of the environment increases).
