A tris β-diketonate europium(III) complex based OLED fabricated by thermal evaporation method displaying efficient bright red emission

An efficient pink luminescent Eu(iii) coordination polymer excited on a blue LED chip

“…The CIE color coordinates of Eu1 fall in the orange region while Eu2 displays typical red emission with CIE color coordinates very close to the National Television System Committee (NTSC) (0.668, 0.325) and thus Eu2 could be a promising candidate as a red component for the fabrication of LEDs. 43 The orange emission of Eu1 could be due to the presence of residual ligand fluorescence, which arose because of the presence of water/DMF molecules in the inner coordination sphere that deactivates the excited state non-radiatively.…”

Internal conversion rate constant calculations considering Duschinsky, anharmonic and Herzberg–Teller effects

“…[6][7][8][9] The most common method for fabricating OLEDs is thermovacuum evaporation. [10][11][12] Although the OLED devices made this way have a high efficiency and lifetime, this method has some shortcomings. First of all, thermovacuum evaporation is expensive and hard to scale for industrial production.…”

Magnetism Studies of Bis(acyl)phosphide-Supported Eu3+and Eu2+Complexes

“…Molecular Eu complexes have continued to gain popularity due to their long-lived luminescence and magnetic properties, making them ideal for numerous applications such as single-molecule magnets and light-emitting diodes. − Many of these complexes are supported by Acac-derived ligands (Acac = acetylacetonate or β-diketonate), with there being over 500 Eu complexes bearing at least three Acac-derived ligands and one neutral supporting ligand in the Cambridge Crystallographic Data Centre (CCDC) . Despite the popularity of Eu 3+ molecular complexes, there have been no reactivity studies of BAP (BAP = bis­(acyl)­phosphide) ligands toward any lanthanide metals.…”
