Luminescence and scintillation properties of VUV scintillation crystals based on Lu-admixed BaY2F8.

Popis výsledku v původním jazyce

Nd and Tm-doped Lu-admixed BaY2F8 crystals were grown by micro-pulling-down method. Lu was added to modify the host matrix to suppress the unwanted energy transfer from exciton levels to the Tm 4f-levels. It was found that low Tm and Nd codoping does notbring much improvement of the scintillation performance and that 1%Nd-doped BaY2F8 single crystal reached nearly the same scintillation efficiency as the LaF3 :Nd one, which is known as a suitable candidate for a VUV scintillator. It is clear there is aconsiderable room for an optimization of this material by changing the Lu/Y ratio and increasing the content of Nd.On the other hand, very high Tm concentrations (around 20%) suppress the excitonic emission (and also the 4f-4f emission) while increasingthe 5d-4f one significantly.
