Three blue fluorescent materials were newly synthesized. A device doped with p-TPA-AP-TPA displayed a very high efficiency of 9.14 cd A−1 and an EQE of 8.38% at a high luminance of 5000 cd m−2.

AbstractIntraday variability is detected in Blazars throughout the electromagnetic spectrum. Only radio emission is affected by interstellar scintillation. The characteristics of variability observed at different frequencies are often similar and suggest that intrinsic variations also contribute to the changes detected in the radio wavelength regime. This in turn implies very high brightness temperatures.Unambiguous signatures of scintillation and of intrinsic changes have been identified. The properties of intrinsic variations are reviewed to illustrate their potential contribution to variability in the radio domain. Such intrinsic changes need to be discriminated against when studying scintillation in quasars and BL Lac objects. Observations of scintillating sources and of sources with significant intrinsic IDV suggest interesting modifications to the standard paradigm of AGN.

The use of a high-brightness field-emission gun (FEG) in scanning electron microscopy (SEM) is a powerful technique to examine microstructures at very high spatial resolution down to nanometer level and has significantly enhanced our ability to solve challenging materials problems, allowing studies of nanoprecipitates.

Carbon nanoforms have emerged as a versatile bioimaging tool. In this work, we have synthesized four different carbon nanoparticles of different dimensions (10–100 nm) and variable fluorescence quantum efficiency (0.007 to 0.37) from four different carbon sources by phosphorus pentoxide-mediated combustion. The fluorescence quantum efficiency of the resulting self-passivated nanoparticles has been empirically correlated to the molecular weight and viscosity of the respective carbon source used in the synthesis. The carbon nanoparticles have been found to be significantly biocompatible as observed in the MTS assay. We have applied these biocompatible luminescent carbon nanoparticles as high brightness fluorescent probes for staining human blood platelets with very high target specificity.

At the tips of sharp needles, the surface electric field is enhanced by many orders of magnitude. This intensifies thermionic emission and photoemission of electrons through the Schottky effect, and reduces the effect of space charge. The increased current density improves the brightness of electron sources by orders of magnitude. In addition, at very high fields (>109 V/m ), field emission and photo-field emission produce very high current density. Arrays of needles can be used to achieve high total current.
