Electroplex emission at PVK/Bphen interface for application in white organic light-emitting diodes

Emitting materials based on phenylanthracene-substituted naphthalene derivatives for organic light-emitting diodes

“…The red-shifted and broad emissions of device B could be originated from these electroplexes. As the operating voltages were increased, some holes could be injected into HOMO of EML more easily and could recombine with the electrons at the LUMO of EML, leading to the enhancement of blue emission from EML and the decrease of ratio of red emission intensity to blue emission intensity [18]. Presumably, the similar EL process would occur in device A and play the significant role in EL properties of device A.…”

“…These observations suggest that the contributions of the other than excimers of 1 and 2 to EL processes of devices using these materials are significant. In some multilayer OLEDs, a bimolecular recombination state called electromers [12][13][14][15][16][17] or electroplexes [18][19][20][21][22] was observed. Electromer is a bimolecular recombination state between hole and electron in EML [12,13].…”

“…Electromer is a bimolecular recombination state between hole and electron in EML [12,13]. The electroplex is a charge transfer state between hole of HTL and electron of EML or hole of EML and electron of ETL, which are found at the HTL/EML interface or EML/ETL interface [18,20]. The .…”

Organic light-Emitting diode based on bis(10-phenylanthracen-9-yl)benzene derivatives with a stable white emission

“…In some multilayer devices, bimolecular recombination state called exciplexes [8,[19][20][21], electromers [7,[22][23][24], or electroplexes [9,[25][26][27] were observed. An exciplex is formed at the organic interfaces between HTL and EML, or EML and ETL, by the 12 different kinds of the two corresponding molecules.…”

Quantum Dot-Based Light Emitting Diodes (QDLEDs): New Progress

“…In recent years, a lot of researches are conducted to achieve efficient and low-energy light sources. Inorganic light emitting diode (LED) and organic light emitting diode (OLED) have been introduced as a result of these efforts to achieve solid-state light sources [1][2][3][4][5][6]. The outdoor application is one of the important markets for LED lighting.…”
