Abstract

Nd3+ doped single crystals, LaBr3:1.25% Nd 3+3+, LaBr3 :2.5% Nd3+3+, LaBr3 :5% Nd3+ and LaBr3 :10% Nd3+3+, were grown by vertical Bridgman process. The scintillation properties including light output, ene rgy resolution, time profile, energy proportionality of the single crystals and the luminescence of polycrystalline power were measured. 2.5% Nd3+ doped LaBr 3 exhibited the best scintillation properties while other doped ones weren’ t so transparent after polished.

Keywords
