Blue organic light-emitting diodes with low driving voltage and maximum enhanced power efficiency based on buffer layer MoO3

Nondoped deep-blue spirofluorenexanthene-based green organic semiconductors (GOS) via a pot, atom and step economic (PASE) route combining direct arylation with tandem reaction

“…In addition, DSA-Ph as a common dopant material [39][40][41][42] and DSFX-TFB were used to fabricate the typical sky-blue uorescent OLEDs with the host-guest structure as reported in the literature. 39 The structure of device F is ITO/MoO 3 (10 nm)/NPB (40 nm)/DSFX-TFB : DSA-Ph (3 wt%, 40 nm)/Alq3 (20 nm)/LiF (0.7 nm)/Al, and the structure of device G is similar to that of device F, apart from the thickness of the emitting layer, which is 50 nm.…”

Electronic, optical, and spectroscopic analysis of TBADN organic semiconductor: Experiment and theory

“…Chen et al [2], Khizar-ul-Haq et al [3], Xu and Khan [4] and Kim et al [5] reported that the energy separation values among the HOMO and LUMO of the TBADN were found to be 3.1, 2.9, 3.0 and 2.9 eV, respectively. Likewise, on that point are many works on molecular structure, spectroscopy (UV-Visible, FT-IR, FT-Raman), and time-dependent density functional theory (TD-DFT) investigations of several materials in the literature [6][7][8][9].…”

The Investigation on Color Purity of Blue Organic Light-Emitting Diodes (BOLED) by Hole-Blocking Layer

“…So far, there is still a distance to achieve standard Commission International de L'Eclairage (CIE) coordinates (0.14, 0.08) of blue OLEDs. Generally, there are many structures of emitting layer to obtain blue OLEDs, such as single emitting layer, double emitting layer, blue guest doped layer, or multiple-quantumwell (MQW) layer [3][4][5][6][7][8][9][10][11][12]. Shi et al utilized MQW structure of [4,4-bis[N-(1-naphthyl)-N-phenylamino]biphenyl (NPB)/ 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP)] that makes hole-electron balance in emitting layer, resulting in the CIE coordinates of (0.1747, 0.1059) [11].…”
