Black-body calculation and schematic illustration of the proposed model.
(a) Black-body radiation calculation in the 1200K ∼ 1300 K temperature region according to Planck’s law. Inset:the variation of monochromic heat flux at 1.42 eV versus temperature gives a slope of 13.09 ± 0.08 in logarithmic coordinate. (b) The formation of the asymmetric APL peak is interpreted qualitatively as an extinction spectrum tailored monodecreasing black-body radiation curve in the corresponding spectral region. (c) The proposed model is illustrated to interpret the origin of the APL from metallic nanowires as an SPR assisted thermal radiation.
