A dodecanethiol-functionalized Ag nanoparticle-modified ITO anode for efficient performance of organic light-emitting devices

Abstract

The electroluminescence intensity of a dodecanethiol-functionalized silver (DT-Ag) NP/ CPB:Ir(mpidmb) 2 (acac) film was increased by about 2.23 times in comparison with that of a control device, CPB:Ir(mpidmb) 2 (acac), due to coupling between excitons of emissive layer and the localized surface plasmon resonance (LSPR) of DT-Ag NPs. The current efficiency of a device with a DT-Ag NPs layer at 100 cd cm À2 (42.3 cd A À1) was 17.0 cd A À1 higher than that of the control device (25.3 cd A À1).The increase in current efficiency in the case of DT-Ag NP-coated devices was strongly related to the energy transfer between radiated light generated from the CBP:Ir(mpidmb) 2 (acac) emissive layer and the LSPR excited by the DT-Ag NPs layer.

Oxide removal and stabilization of bismuth thin films through chemically bound thiol layers

“…The β-methylene and the thiol proton resonate at 1.60 ppm (quintet, J = 7.58 Hz) and 1.39 ppm (unresolved multiplet) respectively, the methyl of the C12 carbon is found at 0.87 ppm (triplet, J = 6.90 Hz) and the remaining protons on C3–C11 form an unresolved multiplet at 1.26 ppm. 37 Fig. 3(b) shows an NMR spectrum of the reaction product formed upon reacting 1-dodecanethiol with Bi powder; two α-methylene groups from a disulphide moiety resonate as a triplet at 2.68 ppm ( J = 7.35 Hz); two β-methylene groups resonate at 1.67 ppm (quintet, J = 7.31 Hz) and between 1.26 and 1.39 ppm there is an unresolved multiplet formed by the protons on the two alkyl chains.…”

Design, fabrication and characterization of capacitive humidity sensors based on emerging flexible technologies

“…The Gaussian decomposition was resolved using the CasaXPS software (from Casa Software Ltd). As can be seen, the laser irradiation is able to break most of the (located at 368.1 eV and 374.1 eV, respectively) [38,39]. These results also present a small content of carbon which remains from the TGME solvent after the drying and sintering steps, as observed in inset of Figure 4c.…”

Magnetic and Highly Luminescent Heterostructures of Gd3+/ZnO Conjugated to GCIS/ZnS Quantum Dots for Multimodal Imaging

“…The ratio used between Cu and In in our research was also 1:1; however, it is noteworthy that our synthesis has differences when compared to the article by Zhang et al, which did not show diffractogram profiles at 2θ smaller 25°. Jayabharathi et al [ 31 ] developed copper/silver nanoclusters protected by DDT. The XRD profiles contained a series of peaks at low angles in the range of 2θ = 10–40°.…”

“…Jayabharathi et al [ 31 ] found two bands for the DDT associated with the asymmetric and symmetric stretching of methylene at 2920 and 2850 cm −1 , 2920 and 2850 cm −1 , respectively. GCIS/ZnS Qdots also have vibrations in these wavenumbers, with the asymmetric vibration at 2920 cm −1 , shifting to around 2917 cm −1 in the conjugated Qdots, which suggests an interaction between the DDT and the conjugated Qdots.…”
