Abstract
In this paper we report on the crystal growth and characterization of 9,10-diphenylanthracene. Crystals of 9,10-diphenylanthracene (DPA) were grown by the solution growth technique as well as the vertical Bridgman method. In case of the solution growth technique, several organic solvents were investigated including heptane, cyclohexane, toluene, and p-xylene. The largest crystals of the highest quality were obtained from toluene and xylene. In the case of vertical Bridgman, evacuated silica ampoules were used to grow large single crystals of DPA. Crystals grown by this method exhibit excellent scintillation properties.Radioluminescence spectra of DPA crystals exhibit a broad emission band peaking at 475nm. DPA crystals show high light yields of up to 20,000ph/MeV and a fast scintillation decay of less than 20ns. Fast neutron detection was achieved using a 252Cf source.
