Untangling the controversy on Ce3+ luminescence in LaAlO3 crystals

Popis výsledku v původním jazyce

We studied a Ce-doped LaAlO3 (LaAP) because of its easy crystal growth facilitated by the large La3+ cations in the matrix. Moreover, recent observations of intense blue luminescence by some researchers show that the potential of this material could not be ruled out. On the other hand, some reports claim that Ce3+ luminescence is completely absent in the LaAP matrix. Therefore, we have decided to study this material in much greater detail using an extended set of correlated experiments to explain the observed discrepancies and underlying phenomena. Crystal growth by the micro-pulling-down method is reported together with the influence of inclusions of other aluminate phases on the luminescence processes. The luminescence mechanism is proposed and discussed and the low scintillation efficiency of the Ce-doped LaAP is explained together with the discrepancies in the literature.
