Healthcare careers for chemists are once again largely based in laboratories, Related Products of 62-23-7, although increasingly there is opportunity to work at the point of care, helping with patient investigation. 62-23-7, Name is 4-Nitrobenzoic acid, SMILES is O=C(O)C1=CC=C([N+]([O-])=O)C=C1, belongs to phthalazine compound. In a document, author is Ye, Shang-Hui, introduce the new discover.
Low cost and high performance white polymer light-emitting diodes (PLEDs) are very important as solid-state lighting sources. In this research three commercially available phosphors were carefully chosen, bis[2-(4,6-difluorophenyl) pyridinato-N, C-2](picolinate) iridium(III) (FIrpic), bis[2-(2-pyridinyl-N) phenyl-C](2,4-pentanedionato-O-2, O-4) iridium(III) [Ir(ppy)(2)(acac)], and bis(2-phenyl-benzothiazole-C-2, N)(acetylacetonate) iridium(III) [Ir(bt)(2)(acac)], plus a home-made red phosphor of tris[1-(2,6-dimethylphenoxy)-4-(4-chlorophenyl)phthalazine]iridium(III) [Ir(MPCPPZ)(3)], and their photophysical and morphological properties were systematically studied as well as their applications in single-emission layer white PLEDs comprising poly(N-vinylcarbazole) as host. Additionally, the electrochemical properties and energy level alignment, possible energy transfer process, and thin-film morphology were also addressed. The binary blue/ orange complementary white PLEDs exhibit stable electroluminescence spectra, wide spectrum-covering region range from 380-780 nm, and high color rendering index (CRI) over 70 with Commission Internationale de l’Eclairage coordinates x, y (CIEx,y) of (0.388, 0.440), correlated color temperature (CCT) of around 4400, plus high efficiency of 25.5 cd A(-1). The optimized red-green-blue white PLEDs showed a satisfactory CRI of around 82.4, maximum current efficiency of 20.0 cd A(-1) and external quantum efficiency (EQE) of 10.8%, corresponding to a CCT of 3700-2800, which is a warm-white hue. At last, stable and high color quality, red-green-orange-blue four component white PLEDs, with a CRI of over 82, a high efficiency of 24.0 cd A(-1), EQE of 11.5%, and high brightness of 43 569.9 cd m(-2) have been obtained.
Related Products of 62-23-7, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 62-23-7 is helpful to your research.
