Abstract

Various yellow-emitting $Y_3Al_5O_{12}:Ce^{3+}$ (YAG:Ce) nanocrystalline phosphors, where some $Al^{3+}$ sites are substituted with $Ga^{3+}$ or some Y sites with Gd3+, have been synthesized. The rare earth ions such as $Pr^{3+}$ and $Tb^{3+}$ were also co-doped into YAG:Ce system, leading to the tunability of CIE coordinates of emission.
