“…A number of studies on the crystallization kinetics of YAG in other systems have been reported [34][35][36][37]. These studies indicate that direct synthesis of YAG is difficult due to the critical influence of the temperature-time history on crystallization pathways.…”

Advanced phosphor materials such as cerium-doped yttrium aluminum garnet (YAG) are of interest for a variety of applications, including light-emitting diodes. Previous studies have shown that it is difficult to produce the desired YAG phase without ex-situ annealing irrespective of the synthesis technique used. This study focuses on direct synthesis of YAG phosphor particles using an inductively coupled thermal plasma system with a ceramic tube inserted coaxially into the chamber. Numerical modeling indicates that the tube provides a more uniform high-temperature region, without flow recirculation. This is hypothesized to aid in size and phase control through selective particle collection and in-flight annealing. Experiments conducted with the tube-insertion setup indicate that phase and size control of the particles is possible to a certain extent, depending on the size of the tube. Characterization results of the synthesized particles showed that submicronsized YAG particles are synthesized as the majority phase through the tube-insertion setup.

“…However, the amount of YAG is quite small as compared to that of h-YAP which appeared at the annealing temperature of 1000°C. It has been reported that the kinetics of phase transformations in the Y 2 O 3 -Al 2 O 3 system is strongly affected by the presence of impurities and defects [12,14,24] or by the degree of crystallinity and homogeneity of the starting materials [13,[25][26][27]. The formation of h-YAP may involve some complicated factors.…”

“…Inner Y 3+ and Al 3+ can be substituted by many kinds of cation with different sizes and valence in a certain extent. Many researchers investigated the effect of doping other ions on host structure and luminescence properties of usual luminescent ions [10][11][12]. However, few literatures reported the luminescence properties of Mn 2+ in YAG.…”
