Figure 5From: Controlling the morphological, structural, and optical properties of one-dimensional PCDTBT nanotubes by template wettingPhotoluminescence spectra. Comparison of PL spectra of (a) PCDTBT nanotubes of 2 h of immersion time and thin film, (b) PCDTBT nanotubes of 24 h of immersion time and thin film, and (c) PCDTBT nanotubes of 2 and 24 h of immersion time.Back to article page
