Effect of polarity in substrate for ZnO growth was researched. The zinc oxide films were deposited on SiOC/Si wafer by a RF magnetron sputtering system. SiOC film was also deposited by RF magnetron sputtering to obtain a low temperature process. Polarity in SiOC film changed with increasing the oxygen gas flow rates, and the chemical shift in the PL spectra was observed because of lowering the ...

The effects of isotope substitution in liquid water are probed by x-ray absorption spectroscopy at the O K-edge as measured in transmission mode. Confirming earlier x-ray Raman scattering experiments, the D2O spectrum is found to be blue shifted with respect to H2O, and the D2O spectrum to be less broadened. Following the earlier interpretations of UV and x-ray Raman spectra, the shift is relat...

In order to develop X-ray probes for Compton scattering on warm dense plasmas K-lines have been investigated by irradiation of solid targets with intense ultra-short pulsed lasers, e. g. spectroscopy of chlorine Kα (2p→ 1s) and Kβ (3p→ 1s) was performed at Europa Laser Facility LLNL. Measurements of the characteristic X-ray emission show that average line positions shift as function of laser en...

2,6-Bis(2-quinolyl)-4(1H)-pyridone 1, a novel quinoline analogue of the well-known ligand 2-terpyridone, shows unusual fluorescence with a large Stokes shift and low energy emission. Pyridine-pyridone tautomerism is investigated by NMR and theoretical methods and indicates that the low energy emission is from the pyridine form. 1 reacts with Ag(i) salts to give a double helical Ag2N6 core showi...

Hue matching was used to obtain measures of Bezold-Brucke hue shifts with very brief flashes (17 msec) at ten wavelengths and several illuminance levels. Results were generally similar to those obtained by Purdy (1931) with uncontrolled stimulus duration. but there were also important differences. These were: the locations of invariant hues; the direction of shift for blue-green hues: and a rev...

An electro-optic tunable single and multi-channel optical filter based on one-dimensional defective photonic crystal (1DDPC) structure is proposed. A couple of externally tunable defects in arrangement of (AB)5D1(BA)D2(BA)5, where A and B are dielectric materials, D1 and D2 are the tunable defects are used. The defects are composed of the ferroelectric LiNbO3 crystals and two pairs of thin Ag l...

Organic light-emitting devices (OLEDs) have attracted lots of attentions and have been subjects of intensive studies due to their great potential for plat panel display and solid state illumination applications. In this paper, we designed a new type of ultra-thin non doped organic blue electrophosphorescent devices of based on Firpic. We also studied that the impact of object layer thickness fo...

Blue light-induced regulation of cell elongation is a component of the signal response pathway for both phototropic curvature and inhibition of stem elongation in higher plants. To determine if blue light regulates cell elongation in these responses through shared or discrete pathways, phototropism and hypocotyl elongation were investigated in several blue light response mutants in Arabidopsis...

A monolithic two-section quantum dot semiconductor laser is differentially pumped to form non-uniform current injection in the gain region. We show that the nature of the spectral content in the output signal is affected by this differential pumping; despite the fact that the separately pumped gain regions are not electrically isolated in this device. Both negative (red-shift) and positive (blu...

Switchable surface redox chemistry is demonstrated in gold@iron/iron oxide core-shell nanoparticles with ambient oxidation and plasmon-mediated reduction to modulate the oxidation state of shell layers. The iron shell can be oxidized to iron oxide through ambient oxidation, leading to an enhancement and red-shift of the gold surface plasmon resonance (SPR). This enhanced gold SPR can drive redu...
