摘要：

We report initial results for a new class of scintillating materials, cerium doped rare earth orthophosphates. The most promising is Ce:LuPO4, which under gamma-excitation shows fast, single-exponential decay, of 25 ns at room temperature, and a light output of 17,200 photons per 1 MeV. These features combined with a reasonable density, (6.53 g/cm3), make it a strong contender for many applications.
