a) TEM image of bare 250 nm BC particles used in study. b) BC absorption cross section (CAbs) as a function of particle mass at λ = 600 nm, 700 nm and 800 nm. c) Absorption spectrum (CAbs) of 250 nm BC from λ = 550 nm to 840 nm. Dashed black line represents AAE fit of the experimental data over full range. Solid red line represents calculated absorption spectrum utilizing T-matrix method described in text. Measured results are reported as experimental mean and 2σ uncertainty propagated across all measurements.
