Light scattering can be used to characterise the physical properties of solid particles (size, refractive index) in dusty plasmas. In the present study, we have collected the dust made in one Argon-silane RF plasma and two Nitrogen-methane RF plasmas. We present polarimetric phase curves of the scattered light obtained ex-situ by the PROGRA 2 experiment. We propose some interpretations in terms of physical properties of the studied particles.
