摘　　要：Four single crystals(Yb_(0.15)Lu_(0.85x)Y_(0.85-0.85x))_3Al_5O_(12)(x=0,0.25,0.5,1)were grown by the Czochralski method.The correlation of the host atom Lu:Y ratios with the density and the luminescence properties were revealed.The density increases linearly with increasing of Lu^(3+)content,which will improve the gamma ray cut-off ability.The integrated intensity of the X-ray excited luminescence spectrum increases exponentially with the increasing Y:Lu ratio,while the decay time becomes even shorter with the increasing Lu^(3+)content.These results will provide a basis to balance the comprehensive properties to match different application requirements.
