Photoluminescence Characteristics of Dendrimers Containing (tris (8-hydroxyquinoline) aluminum) as a Core Unit

Adsorption of tris(8-hydroxyquinoline)aluminum molecules on cobalt surfaces

We studied the adsorption of tris(8-hydroxyquinoline)aluminum (Alq3) molecules on cobalt surfaces using density functional theory with the generalized gradient approximation. The van der Waals interaction between Alq3 molecules and cobalt surfaces was included by the dispersion correction. Magnetization of Alq3 molecules, adsorption energies, and bonding energies were obtained for smooth and de...

Formation and Entrapment of Tris(8-hydroxyquinoline)aluminum from 8-Hydroxyquinoline in Anodic Porous Alumina

The formation and entrapment of tris(8-hydroxyquinoline)aluminum (Alq₃) molecules on the surface of anodic porous alumina (APA) immersed in an ethanol solution of 8-hydroxyquinoline (HQ) were investigated by absorption, fluorescence, and Raman spectroscopies. The effects of the selected APA preparation conditions (galvanostatic or potentiostatic anodization method, anodizing current and voltage...

Spectroscopic Evidence of Photodegradation by Ultraviolet Exposure of Tris(8-hydroxyquinoline) Aluminum (Alq3) Thin Films

A degradação extrínseca de diodos orgânicos emissores de luz (OLEDs) permanece como uma questão crucial, especialmente no que se refere à degradação, devido à exposição à luz. Poucos estudos existem e faltam dados a respeito dos produtos de fotodegradação e respectivos mecanismos, responsáveis pela extinção da luminescência. Com o objetivo de investigar os mecanismos de degradação causados pela...
