Luminescent and scintillation properties of the Ce3+ doped Y3-xLuxAl5O12:Ce single crystalline films

The work is related to the investigation of scintillation and luminescent properties of single crystalline films (SCF) of solid solutions of Ce3+ doped Y3-xLuxAl5O12:Ce garnets with x value in the 0-3 range. We have shown a possibility of realization of high-energy shift of the Ce3+ ion emission spectrum in these garnets up to 22 nm. We have also found that the light yield of the radioluminescence under alpha-particle excitation of LuAG:Ce SCF can exceed by 1.3 times the corresponding values for the YAG:Ce SCF counterpart. For investigation of the luminescent properties of Y3-xLuxAl5O12:Ce SCF at different x values the luminescent spectroscopy of these SCFs under excitation by synchrotron radiation in the VUV range was performed.
