“…The energy band diagrams of the Alq3-network were determined from the highest occupied molecular orbital (HOMO) and lowest unoccupied molecular orbital (LUMO) energy levels and the band gaps calculated from CV [28]. The HOMO energy level of the complexes was evaluated by CV on an electro-chemical workstation.…”

A solution processable hybrid organic-inorganic composite functionalized with Alq3 was used as an emitting layer in an OLED device. The advantage of the spin-coated films is its ease of layer deposition method to replace physical vapor deposition. Investigation of chemical structure of these networks was performed by different techniques including 1 H-NMR, FT-IR, DSC and SEM. Results revealed that a silicone based structure was produced in which Alq3 has been attached to silane precursor through amine groups of silane and sulfonic functionality of 8-hydroxyquinoline. Electrical behavior of the samples was measured by cyclic voltammetry method. Photoluminescence and electroluminescence analyses showed that hybrid organic-inorganic Alq3-network can be used in OLED devices to replace conventional Alq3. While the band gap of the pristine Alq3 is 2.70 eV, that of the silane modified Alq3 has shifted to 2.83 eV. This shows a blue shift in emitted color.

“…Recently, Alq 3 molecules have been incorporated into various sol-gel matrices for studying their static [15] and dynamics [16] spectroscopic behaviors, and interesting results concerning energy transfer, lifetime and photostability have been obtained, but other experimental results were not taken in full consideration. For instance, blueshifts were evident in a few emission bands, so that it was decided to perform a new systematic spectroscopic analysis on all the measured emission bands to verify the existence of a well-defined trend for the apparent blueshifts.…”
