1. Introduction
Due to the high transparency and the stable physical–chemical properties, yttrium aluminum garnet (YAG) materials have attracted considerable attention for their possible application as the gain media of laser materials (doped with Nd3+, Yb3+, Er3+) [1], [2] and [3], scintillation materials (doped with Ce3+, Gd3+) [4] and fluorescent materials (doped with Ce3+) [5].
