Abstract:

Bi 3+,  Eu 3+ , Tb 3+ doped  Lu3TaO7 were synthesized by solid reaction method. The powders were characterized by XRD patterns, excitation, emission spectra and decay curves. All of  Lu3TaO7 doped by the three kinds of ions show the considerable strong luminescence, Bi 3+ presents a broad emission band peaking at 431 nm and the decay time is 16.8μs, Eu 3+ , Tb3+ show the typical sharp emission peaks of rare earth ions and the decay times are 1.26 ms and 1.20 ms, respectively. So they can be applied as potential high-density scintillators.

Key words: materials; scintillator; Lu3TaO7; luminescence
