In article number 1904390, Lena Yadgarov and co‐workers present how the extinction spectrum of size‐fractionated nanotubes show that WS 2 nanotubes with (average) diameter larger than 80 nm exhibit strong coupling effect (polaritons) and scatter light, while nanotubes with diameter below 60 nm show pure absorption with the A, B and C excitons clearly visible in the spectrum.
