Fig. 2: Optical properties of chiral- and racemic-NPB.

a UV–Vis linear absorption spectra and b circular dichroism (CD) spectra recorded at room-temperature for thin films of racemic-, R- and S-NPB. c, d Photoluminescence spectra from single crystals of racemic-, R- and S-NPB obtained at c room-temperature using a 325 nm laser source, and at d 7 K using a 266 nm laser source; FE and STE denote free excitons and self-trapped excitons, respectively.
