Abstract
Abstract Photoluminescence, scintillation and thermoluminescence properties of undoped and Ce-doped SrLaAl3O7 crystals grown using the optical Floating Zone technique were examined. An intense broad emission peak at 400 nm are observed from photoluminescence excitation-emission maps and scintillation spectra of the Ce-doped SrLaAl3O7 crystals, with the origin is ascribed to the 5d-4f transitions of Ce3+. The primary decay of the Ce-doped and undoped SrLaAl3O7 crystals are attributable to the Ce3+ ions and intrinsic luminescence, respectively. The 3.0% Ce-doped SrLaAl3O7 crystal shows the highest light yield of 760 ph/5.5 MeV-α among the investigated samples based on pulse height analysis under α-rays excitation from 241Am.
