Triplet Emitters for Organic Light‐Emitting Diodes: Basic Properties

Organometallic Materials for Electroluminescent and Photovoltaic Devices

“…(14), to ZFS of the T 1 (n-π*) state. Similar analysis has been presented for the Ir(ppy) 3 complex Yersin & Finkenzeller, 2008), which shows that the SOC splitting of the 3 MLCT state can be relatively large. Let us use the perturbed states, Eq.…”

“…Principles of electro-luminescence in organic polymers are described in a number of references (e.g. Pope & Swenberg, 1999;Yersin & Finkenzeller, 2008;Köhler & Bässler, 2009). In this review we concentrate our attention on the theoretical description of molecular states at the microscopic level; thus the macroscopic picture of the structural elements of OLEDs and photovoltaic devices will be shortly presented in the form of main concepts of their architecture, connected with organic and inorganic materials in different aggregate states.…”

“…Twenty-four years later the pioneering work of Eastman Kodak Company (Tang & VanSylke 1987) provided the use of 8-hydroxyquinoline aluminum (Alq 3 ) as electron-transporting and emissive material (Scheme 1) in an OLED device. Since then a growing progress has been witnessed in the field of organic optoelectronics through incorporation of various combinations of organic polymers, dyes and organometallic complexes (Yersin & Finkenzeller 2008, Köhler & Bässler 2009). Organic conjugated polymers, like poly(para-phenylene vinylene) (PPV) doped by various chromophores, are now used in OLEDs as they lend the possibility to create charge carrier recombination and formation of excitons with high efficiency of light emission.…”

Vibration Correlation Function Investigation on the Phosphorescence Quantum Efficiency and Spectrum for Blue Phosphorescent Ir(III) Complex

“…最后, 结 合分子的跃迁性质, 使用本组自主发展的光谱和速率理 论程序, 计算出有机过渡金属配合物 fac-Ir(F 2 ppy) 3 在不 同温度下的磷光光谱、辐射衰减速率和系间窜越速率、 磷光效率及激发态寿命. [30] . 温度再升高, 三个子电子态会 按照一定方式分布, 像波尔兹曼分布, 不可区别.…”

Investigação teórica da agregação de complexos catiônicos de Ir (III) com potencial aplicação em <i>LEEC\'s</i> e <i>OLED\'s</i>

“…OLED's), assim como células eletroquímicas emissoras de luz (do inglês, Light-Emitting Electrochemical Cells, LEEC's) vem sendo intensamente investigados por possuírem grandes potenciais de aplicação nas áreas de iluminação e em tecnologia de displays flexíveis [1][2][3] . Os dispositivos luminescentes são baseados na emissão das três cores primárias (vermelho, verde e azul) [4][5][6][7] , sendo que emissores de luz vermelha e verde já foram reportados com boa eficiência quântica interna (IQE).…”
