Description

technical field [0001] The invention belongs to Nd-doped 3+ Technical field of ionic yttrium aluminum garnet powder. Specifically related to a Nd-doped 3+ Ionic yttrium aluminum garnet powder and its preparation method. Background technique [0002] In recent years, rare earth doped yttrium aluminum garnet powder has been widely used in optics, detection, medical and other fields. For example, in order to make yttrium aluminum garnet (YAG) have laser emitting ability, doping a certain amount of rare earth Nd 3+ Nd-doped yttrium aluminum garnet (Nd:YAG) was prepared. Nd:YAG is part of the Yttrium Aluminum Garnet crystal that will act as a matrix Y 3+ By the activated ion Nd 3+ Instead, to form Nd:YAG solid solutions, Nd:YAG lasers are currently the most commonly used class of solid-state lasers. During the preparation of YAG single crystal, Nd 3+ The segregation coefficient in a YAG single crystal with a complete structure is only about 0.2, if doped with Nd 3+ If th...
