“…In the case of OxFl spectra, an additional peak (at around 309 nm) with slow intensity appeared, which originates from fluorene unit. 31 The first absorption maximum was attributed to the π – π * transitions of the aromatic chromophore (phenylene units), while the second maximum is due to n – π * and π – π * transitions from all conjugated molecules (i.e. C=N bonds, fluorene, and 1,3,4-oxadiazole units).…”

“…In contrast, the Alq 3 embedded into PVA thin film shows similar FTIR spectrum as PVA thin film except for the appearance of three peaks at 2176, 1580, and 750 cm −1 . The 2176, 1580, and 750 cm −1 peaks correspond to Al-O-H, C = N, and Al-N modes for Alq 3 chemical bonding [46][47][48], respectively. The SEM image of Alq 3 :PVA thin film was also obtained as shown in Fig.…”
