Punia, Monika; Khatkar, Satyender Pal; Taxak, Vinod Bala; Dhankhar, Priyanka; Boora Doon, Priti published an article in 2021. The article was titled 《Synthesis of cool white light emitting novel dysprosium (Dy3+) complexes with tetradentate β-ketoamide and heterocyclic auxiliary ligands》, and you may find the article in Luminescence.Computed Properties of C12H12N2 The information in the text is summarized as follows:

To improve current multiphase white light emitting diodes (WLEDs), a novel series of five complexes consisting of one binary and four ternary complexes that emitted cool white light was successfully synthesized using a chelating tetradentate ligand and auxiliary ligands, i.e. 5,6-dimethyl-1,10-phenanthroline, 1,10-phenanthroline, 4,4′-dimethyl-2,2′-bipyridyl, and 2,2′-bipyridyl. The series was examined structurally using elemental anal., Fourier transform IR spectroscopy, energy dispersive X-ray anal., UV-visible spectroscopy, and proton NMR spectroscopy. These complexes had the appropriate thermal stability required for the generation of white organic LEDs (WOLEDs). Dysprosium (III) (Dy3+) ion complexes demonstrated the characteristic emission peaks of blue color at 482 nm and yellow color at 572 nm, resp., when excited using near UV light. Band gap, refractive index, and decay lifetime of the optimized samples were recorded as 2.68 eV, 2.12, and 1.601 ms, resp. Correlated color temperature value (7875 K), Commission International de l′Eclairage coordinates (0.300, 0.294), and color purity (21.04 x 10-2) of the optimized complex were near to those of white illuminants as defined by the National Television System Committee. These complexes had promise as com. LEDs for the advanced optoelectronics devices, especially as WOLEDs for illumination applications. In the experiment, the researchers used many compounds, for example, 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Computed Properties of C12H12N2)
