Alq₃ Nanorods: Promising Building Blocks for Optical Devices

Abstract

Monodisperse Alq3 nanorods with hexagonal-prism-like morphology are produced via a facile, emulsion based synthesis route. The photoluminescence of individual nanorods differs from the bulk material. These nanorods are promising building blocks for novel optical devices.

Spectral characterizations and photophysical properties of one-step synthesized blue fluorescent 4′-aryl substituted 2,2′:6′,2′′-terpyridine for OLEDs application

“…al. suggested that luminescence of the materials increase with crystalline nature [42]. Further, it can be inferred from the SEM micrographs that the rods are well distributed without exhibiting formation like cluttering, and distortion.…”

Fac‐Alq3 and Mer‐Alq3 Nano/Microcrystals with Different Emission and Charge‐Transporting Properties

“…These two isomeric forms exhibit quite different physical properties such as color and fluorescence, that is, green emission for light‐yellow mer ‐Alq 3 and blue emission for whitish fac ‐Alq 3 . Along with the progress on the studies of Alq 3 bulk materials, increased effort has been directed toward the construction of Alq 3 ‐based nano or microstructured materials, particularly, 1D nanostructures, to further understand their photophysical properties in the nanoscale and explore novel optoelectronic applications 16–22…”

“…It was demonstrated that the fac ‐Alq 3 crystalline phase could only be achieved by annealing mer‐ Alq 3 at around 400 °C for at least several tens of minutes 12. Therefore, the reported approaches such as vapor deposition and a solution‐based route,16–21 which have been employed to prepare mer‐ Alq 3 nanocrystals, are not suitable for the fabrication of fac ‐Alq 3 nanocrystals. From this viewpoint, the development of an efficient approach suitable to prepare fac ‐Alq 3 nanocrystals is a highly important issue regarding the fundamental physical properties of fac ‐Alq 3 ‐based nanostructures.…”

Preparation of 8-hydroxyquinoline wires by decomposition of tris(8-hydroxyquinoline) aluminium

“…Thus, due to a variety of technological applications of HQ, the synthesis of the novel morphologies of HQ and study of their properties is of interest. The growth of various Alq 3 structures and their properties has been reported [15][16][17][18][19], both in nanostructured and thin film forms have been extensively studied [15][16][17][18][19][20][21][22]. The growth of nanowires of other quinoline derivatives, such as cadmium (II) (HQ) chloride, has also been reported [23].…”
