TLDR
In this article, a stable organic electroluminescent devices based on vapor-deposited Alq thin films have been achieved, which are derived from several factors including: (1) a multilayer thin-film structure with a CuPc stabilized hole-injection contact, (2) a hole-transport diamine layer using a naphthyl substituted benzidine derivative, and (3) an ac drive wave form.Abstract:
Highly stable organic electroluminescent devices based on vapor‐deposited Alq thin films have been achieved. The improvement in stability is derived from several factors including: (1) a multilayer thin‐film structure with a CuPc stabilized hole‐injection contact, (2) a hole‐transport diamine layer using a naphthyl‐substituted benzidine derivative, and (3) an ac drive wave form. These emissive devices have shown an operational half‐lifetime of about 4000 h from an initial luminance of 510 cd/m2.read more

Simultaneous color and luminance control of organic light-emitting diodes for mood-lighting applications
TL;DR: A pulse-width-modulation-based driver concept is introduced, enabling the user to simultaneously and independently adjust color and luminance of a single device with two contacts, which makes color-shifting OLEDs highly interesting for “mood-light” applications.

Theoretical investigation of the structure and electronic absorption spectrum of a complex zinc bis-[8-(3,5-difluorophenylsulfanylamino)quinolinate]
TL;DR: Using the quantum-chemical methods of the density functional theory DFT/B3LYP/DGDZVP, of the electron density topological analysis QTAIM, and of the time-dependent density functional theories TDDFT/BMK/DDDZVP as mentioned in this paper, the structure and spectral properties of the electroluminescent complex zinc bis-[8-(3,5-difluorophenylsulfanylamino)quinolinate] have been studied.
