We report the first measurements of the interaction of non-equilibrium phonons with twodimensional exciton gases (2DExGs). The rise in the effective temperature of the 2DExG produced by the phonons depends on the width of the quantum well and the exciton sheet density and hence on the ratio 5 -l (ex
