Abstract:
Luminescence properties of square-planar complexes of platinum(II) and palladium(II) with a d8 electron configuration were investigated. Blue shift of the maxima of the luminescence spectra occur for pressure-dependent spectra of several complexes of both metals. This is due to a structural compression of the crystalline lattice, which causes a destabilization of the LUMO orbital for theses complexes. Other structural changes can also occur, providing a more important slope of the blue shift. Also, intermolecular interactions cause a red shift in pressure-dependent spectra. In temperature-depe

Abstract:
The magnetic response of the near-band-edge optical properties is studied in EuTe layers. In several magneto-optical experiments, the absorption and emission are described as well as the related Stokes shift. Specifically, we present the first experimental report of the photoluminescence excitation (PLE) spectrum in Faraday configuration. The PLE spectra shows to be related with the absorption spectra through the observation of resonance between the excitation light and the zero-field band-gap. A new emission line appears at 1.6 eV at a moderate magnetic field in the photoluminescence (PL) spe

Abstract:
Reflectance spectra allow the early detection of stressors causing differences in pigment content as well as changes of leaf tissue structure and photosynthetic activity. The reflectance decreased with increasing Chl content in greening bean leaves. In stressed leaves, in turn, the reflectance increased with decreasing Chl content. This also caused a shift of the red reflection rise (“red edge”) to shorter wavelengths (“blue shift”) associated with a blue shift of the inflection point of the red edge. The contribution of the red and far-red Chl fluorescence to the reflectance signal at the red

Abstract We investigate electron spin resonance (ESR), absorption, and photoluminescence spectra of potassium-boron copper-containing glasses. In previous works it was found, that the considered glasses demonstrate a red shift of photoluminescence. In present work, we provide an evidence on the formation in glasses specific copper-containing structures that can be responsible for the red shift of photoluminescence “copper” band.

Abstract:
Solvatochromism and thermochromism of 4-aminophthalimide and 4-amino-N-methylphthalimide were studied by absorption and steady-state and time-resolved emission spectroscopy in solvent mixtures of toluene­ethanol and toluene­acetonitrile at different temperatures. Emission spectra shift to the red upon addition of a polar solvent (PS) to toluene. Solvent mixtures show a much greater thermochromic shift to the blue in emission than the neat solvents. This is explained by the decrease in temperature of the exothermic association of the polar solvent to the excited state. Emission spectra are time

AbstractThe structural and spectral properties of coumarin derivatives in complex environments were investigated within the time-dependent density functional theory (TD DFT). Absorption spectra calculations were obtained at TD PBE0/6-31+G(d,p) level of theory for coumarin47 in the gas-phase and in various polar and non-polar organic solvents. The geometries of coumarins 6, 30, 47 and 522 in the gas phase and in inclusion complexes with the β-cyclodextrin (βCD) were determined by PM3 and DFT (HCTH/6-31G) calculations.

Abstract:
This chapter sets out the ‘Red-Green’ alternatives which combine environmental and socialist perspectives and policies irreconcilable with the logic of market capitalism. ‘Red’ is taken to stand for the struggle for social justice and ‘Green’ for defence of the environment, including, of course, the effects of climate change. The chapter discusses these issues in the international as well as the British context. It contends that the green movement’s more radical wings offer the most complete, alternative to neoliberalism’s ‘full spectrum dominance’ and the chimera of ‘sustainable capitalism’. ‘Social greens’ advocate a profound shift in values, decentralised decision making, more participative democracy, and localised instead of corporate and international market economies. Further, the chapter argues for the development of a positive, non-exploitative relationship between people and non-human nature and, similar to Coote in chapter 2, for convivial interactions reflecting an ‘alternative hedonism’ to inflated commercially-based consumerism. Such a mutually beneficial and pleasurable social relationship offers the positive psychological and cultural dimension to the ‘Red-Green’ project that the stark demand to take less of the earth’s resources lacks.

Abstract:
This chapter shows that in the limit of weak fields and low velocities, the equation of the geodesic line reduces to Newton's equation of motion. It proceeds to derive the gravitational field equation. Next, the chapter uses the gravitational field equation to derive the three effects that served as the first tests of the theory: the bending of light by the gravitational field of the sun, the shift to the red of spectral lines emitted by atoms in a gravitational field (gravitational redshift), and the motion of the perihelion of planet Mercury. After a short remark about expressing Maxwell's equations of the electromagnetic field, the chapter turns to the “so-called cosmological problem.” Its main theme is the defense of Mach's principle, which states that all inertial phenomena, namely the fictitious forces arising in accelerated reference frames, are caused by all the masses in the universe.

Abstract:
The calix[4]arenes (abbreviated as CX[4]) are characterized by a specific hydrophobic cavity formed by a four cyclically phenol groups to encapsulate a gas or small molecules. Recently, the CX[4] molecule is used in a specific media and in pharmaceutical drug delivery. The pollution problem will be a vital subject in the future because the increase of the explosions of the gaseous pollutants in the environment. In this report, we have encapsulated the polluting gases NO3, NO2, CO2 and N2 by the calix[4]arene molecule. In this work, The binding energies of the CX[4]-gas has been calculated including the BSSE (Basis Set Superposition Error) counterpoise (CP). The red-shift of the O-H bonding interactions obtained by adding the gas in the sensitive area of calix[4]arene is clearly explained by the infrared spectrum analysis. The Molecular electrostatic potential (MEP) of the stable CX[4]-gas complexes have been investigated in the endo-vs. exo-cavity regions. Finally, the non-covalent interactions analyses of the stable host-guests complexes have been estimated by using DFT calculations.

In this paper, we will characterize the performance of the camera using 32 nm and 22 nm SOI chips.
