چکیده

High-quality pentacene-doped p-terphenyl bulk crystals were grown by the selective self-seeding vertical Bridgman technique (SSVBT). The lattice structure and crystal properties of samples different doping concentrations their relations with single tested analyzed. effects pentacene at in molecular are discussed. powder X-ray diffraction, FTIR, 1H NMR studies show that no additional peaks (except for p-terphenyl) observed spectra two doped crystals. results indicate guest molecules appear as defects form irregularly oriented which do not significantly change structures. As concentration increases, average crystallite size decreases, crystallinity declines. ultraviolet–visible absorption fluorescence added molecules, characteristic peak intensities decrease owing to transition. Meanwhile, due Moreover, increase concentration, host continuously, those accordingly.

Conformation 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...

Investigation 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...

Soft-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...
