Abstract
It is shown theoretically that the emission efficiency of amorphous grains with radii smaller than ∼100 Å has a λ-1-dependence in the wavelength region longer than ∼100 μ, whereas those of crystalline, metallic, and larger amorphous grains are proportional to λ-2 in far infrared. Astrophysical implications of the amorphous grains are discussed.
