Abstract

Abstract : In article number 1904390, Lena Yadgarov and co‐workers present how the extinction spectrum of size‐fractionated nanotubes show that WS2 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.
