The formation of an oxide film on the surface of an aluminum particle significantly changes the conditions of propagation of radiation inside such a two-layer particle, and this results in a significant increase of the relative fraction of the energy absorbed in it. For the range of particle sizes studied (0.1 < R < 20 μm) even a not very large oxide shell, whose thickness comprises approximately 10% of the radius of the particle, increases the absorption of radiation by a factor of 15 compared with a metal particle of the same size.
