(Lu/sub x/Y/sub 1-x/)AP:Ce scintillation crystals

REAlO/sub 3/:Ce/sup 3+/ (RE=Y, Lu) scintillation crystals have impressive prospects for wide application in many branches of industry and are now being actively investigated. Here we report the scintillation mechanism in these crystals and possible ways of their scintillation properties improvement. The scintillation properties of (Lu/sub 0.5/-Y/sub 0.5/)AlO/sub 3/:Ce and (Lu/sub 0.7/-Y/sub 0.3/)AlO/sub 3/:Ce scintillation crystals grown under the mass production conditions also have been discussed.
