This study investigates the temporal evolution of the infrared emission from the dusty nova V1280 Sco over 2000 days from the outburst. We have revealed that the infrared spectral energy distributions at 1272, 1616 and 1947 days are explained by the emissions produced by amorphous carbon dust of mass (6.6-8.7) × 10-8 M⊙ with a representative grain size of 0.01 μm and astronomical silicate dust of mass (3.4-4.3) × 10-7 M⊙ with a representative grain size of 0.3-0.5 μm. Both of carbon and silicate dust travel farther away from the white dwarf without an apparent mass evolution throughout those later epochs.
