Biosubstrates Obtained from Gellan Gum for Organic Light-Emitting Diodes
(2021-01-01)
Nowadays, flexible organic electronics are under intense investigation for environmentally friendly and biocompatible applications. One of the main components of electronic devices is the substrate, which gives support for ...
Modelagem e acionamento de diodos orgânicos emissores de luz (OLEDs) para sistemas de iluminação
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2015-08-26)
This thesis presents the study and characterization of organic light-emitting diodes
(OLEDs) with the proposal of obtaining an equivalent model that is useful in the OLED driver
design and in lighting systems projects. ...
Femtosecond-laser direct writing for spatially localized synthesis of PPV
(Journal of Materials Chemistry C, 2018)
Transparent bacterial cellulose nanocomposites used as substrate for organic light-emitting diodes
(2019-01-01)
In this work, high transparent bacterial cellulose (HTBC) biocompatible membranes were produced to be used as substrates in organic light-emitting diodes (OLEDs). These multifunctional membranes are based on bacterial ...
Fast and cost effective fabrication of microlens arrays for enhancing light out-coupling of organic light-emitting diodes
(Elsevier Science, 2019-10)
The efficiency of organic light-emitting diodes (OLEDs) deposited on flat substrates is strongly limited by the total internal reflection at the air-substrate interface. An effective strategy to reduce the amount of substrate ...
Luminous efficiency enhancement of PVK based OLEDs with fac-[ClRe(CO)(3)(bpy)]
(ELSEVIER SCIENCE SA, 2011)
The luminous efficiency of organic light-emitting diodes based on poly(N-vinylcarbazole), PVK, was improved by adding fac-[ClRe(CO)(3)(bpy)], bpy = 2,2`-bipyridine, to PVK host. Emissive layers with various Re(I) complex/host ...
Magnetic field effects in Alq3-based OLEDs investigated by electrical impedance spectroscopy
(2017-11-01)
The effect of an external magnetic field on electrical impedance was measured on tris-(8-hydroxyquinoline) aluminum (Alq3) based OLEDs at different temperatures. Magnetic field effects (MFEs) were responsible for significant ...
Extraction of 2′-O-apiosyl-6′-O-crotonic acid-betanin from the ayrampo seed (Opuntia soehrensii) cuticle and its use as an emitting layer in an organic light-emitting diode
(Royal Society of Chemistry, 2020)
The molecule 2′-O-apiosyl-6′-O-crotonic acid-betanin (called Achkiy) was obtained after an ecofriendly and low-cost purification process of the extract from the ayrampo seed cuticle. Results from EDS give us an idea of the ...
