Crystal growth and spectral properties of (Yb<sub>0.15</sub>Lu<sub>0.85x</sub>Y<sub>0.85-0.85x</sub>)<sub>3</sub>Al<sub>5</sub>O<sub>12</sub> single crystals [Early Posting]
Four single crystals (Yb<sub>0.15</sub>Lu<sub>0.85x</sub>Y<sub>0.85-0.85x</sub>)<sub>3</sub>Al<sub>5</sub>O<sub>12</sub> (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<sup>3+</sup> content, which will improve the gamma ray cut-off ability. The integrated intensity of the XEL spectrum increases exponentially with increasing the Y:Lu ratio. While the decay time becomes even shorter with increasing the Lu<sup>3+</sup> content. These results will provide a basis to balance the comprehensive properties to match different application requirements.
