| 英文摘要 | At present, research into optical properties of bio-smoke materials mostly concentrates on single band or single germplasm. Herein, we measured the spectral reflectance of three eukaryotic bio-smoke materials and three prokaryotic bio-smoke materials in the waveband from 0.25 μm to 14 μm. Based on the Kramers–Kroning algorithm, the complex refractive index m(γ) was calculated and the Fourier-transform infrared (FTIR) spectra of materials were analyzed. The results show that n(γ) of bio-smoke materials varies between 1.1–2, and n(γ) values in the visible light to near-infrared wavebands are significantly larger than those in other wavebands. The k(γ) of bio-smoke materials varies between 0–0.4. At 6–6.5 μm, k(γ) of prokaryotic materials is 3 times that of eukaryotic materials, which is caused by C=O stretching vibration of amide I and C–N stretching vibration of amide II in proteins. At 2.5–3 μm and 9.75 μm, k(γ) values of eukaryotic bio-smoke materials are nearly 2 times that of prokaryotic ones. The absorption peak at 2.5–3 μm is mainly triggered by C–H stretching vibration in lipid and O–H stretching vibration in bound water. The absorption peak at 9.75 μm is mainly caused by symmetric stretching vibration of PO_2~- in nucleic acids. |
