Fig. 1. (a) Steady-state absorption and photoluminescence spectra of Cz⁹PhAn in CH₂Cl₂ and film (prepared via thermal evaporation). Blue and orange dashed lines represent the spectral decomposition of the film photoluminescence spectrum (see text for assignments and details). The asterisk shows the excitation wavelength. (b) Steady-state spectra of Cz⁹PhAnt film and 3 wt% Cz⁹PhAn doped in a common host (prepared via thermal evaporation).
