Some Luminescant Properties of the Mixed Phenyl- and p-Biphenylyl-Substituted Silanes under Ultra-Violet, Gamma and Beta Excitation
Abstract
Luminescent properties of triphenyl-p-biphenylylsilane (silane I), biphenyl-di-p-biphenylylsilane (silane II) and phenyl-tri-p-biphenylylsilane (silane III) have been investigated. In comparing these phosphors with anthracene the following results were obtained: (a) Silane I is 8% less effective than anthracene in its gamma detecting ability. (b) The pulse height of the silanes is about 40% - 45% that of anthracene. (c) Each of the silanes is about 70% as efficient a beta detector as anthracene. Fluorescence spectra for each of the silanes under ultraviolet and beta stimulation are reported. Peak emission wave-lengths are 400, 400, and 450 millimicrons for Silane I, II, and III respectively. Fluorescence decay constants of 2.53-2.54, 2.62-2.63 and 3.29-3.31 nanoseconds were found for Silane I, II, and III.
