Neutron Scattering Studies of the Model Glass Former Ortho-terphenyl
The van der Waals liquid orthoterphenyl has long been used as a model system in the study of the glass transition. Motivated by mode–coupling theory, extensive experiments have been undertaken to monitor the onset of structural relaxation on microscopic time and length scales. Using in particular quasielastic neutron scattering, the decay of density and tagged–particle correlations has been mea...
متن کاملConformation of p-terphenyl under hydrostatic pressure.
The conformation of p-terphenyl (C18H14) and deuterated p-terphenyl (C18D14) has been investigated, using high-pressure infrared spectroscopy at liquid-helium temperatures. First-principles calculations, together with the experimental results, were performed to determine the structure of p-terphenyl in the twisted conformation. At low temperatures and pressures, p-terphenyl belongs to the C2 po...
متن کاملLigand influences on homoleptic Group 12 m-terphenyl complexes.
Three m-terphenyl ligands 2,6-Ar2C6H3(-) [Ar = 2,6-Me2C6H3 (2,6-Xyl); 3,5-Me2C6H3 (3,5-Xyl); 2,3,4,5,6-Me5C6 (Pmp)] have been used to stabilise three series of two-coordinate Group 12 diaryl complexes; (2,6-Ar2C6H3)2M [M = Zn, Cd, Hg, Ar = 2,6-Xyl 1-3, 3,5-Xyl 4-6, Pmp 7-9], where differing steric demands on the metal centres are imparted. These are the first homoleptic d-block complexes featur...
متن کاملSoft-x-ray damage to p-terphenyl coatings for detectors.
The organic phosphor p-terphenyl is used as a wavelength-converter coating in some soft-x-ray detectors. We have measured the absolute photoluminescent efficiency of p-terphenyl as a function of incident photon energy from 36 to 191 eV. We have also measured changes in the efficiency caused by soft-x-ray fluence (total photons absorbed per unit area) at several photon energies in this range. We...
متن کاملInvestigation of wavelength shifter properties of p-terphenyl and TPB
Wavelength shifter materials like pTerphenyl and Tetra Phenyl Butadiene (TPB) of thicknesses between 65 and 250 μg/cm have been studied in order to improve the quantum efficiency (QE) of a photomultiplier in the UV range. The best result has been obtained for p-Terphenyl of 100 μg/cm thickness. In this case the quantum efficiency integrated over a broad range of photon energies up to 6.2 eV sho...
