Spectral-Luminescence and Scintillation Properties of p-Terphenyl Single Crystal Grown from Melt

The results of the study of the photoluminescent and X-ray luminescent properties of a p-terphenyl crystalline element made of a single crystal grown from a melt using the Bridgman method are presented. The transmission, photoluminescence, and X-ray luminescence spectra of the crystals were obtained and analyzed. The kinetics of photoluminescence and X-ray luminescence decay have been studied for p-terphenyl single crystal, and the absolute light yield of X-ray luminescence has been determined.
