## Description

- description: 'Environmental-friendly alternatives to the commercial scintillator
    CdWO4, which contains the toxic element Cd, are highly desired. As potential candidates,
    in this work, the scintillation characteristics of Nb:YTaO4 transparent single-crystals
    grown from melt by the floating-zone technique are studied. It is found that the
    broad UV luminescence of YTaO4 can be turned into a broad visible one by the partial
    substitution of Ta with only 2% Nb. Therefore, Nb incorporation promotes a better
    spectral matching to Si-photodiode detectors while the high stopping power of
    YTaO4 is kept, being close to that of commercial CdWO4. The scintillation properties
    of pure YTaO4, with a light yield of 15900 ph/MeV and an afterglow of 0.008% after
    40 ms, are comparable to those of CdWO4. The light yield weighed with a Si-photodiode
    reaches maximum values for 0.5 & 1% Nb:YTaO4 crystals. An improvement in optical
    properties is expected by the growth of higher quality crystals by a flux-technique
    in the future.  '
