The renowned yellow phosphor yttrium aluminum garnet (YAG) doped with trivalent cerium has found its way into applications in many forms: as powder of micron sized crystals, as a ceramic, and even as a single crystal. However, additional technological advancement requires providing this material in new form factors, especially in terms of particle size. Where many materials have been developed on the nanoscale with excellent optical properties (e.g., semiconductor quantum dots, perovskite nanocrystals, and rare earth doped phosphors), it is surprising that the development of nanocrystalline YAG:Ce is not as mature as for these other materials. Control over size and shape is still in its infancy, and optical properties are not yet at the same level as other materials on the nanoscale, even though YAG:Ce microcrystalline materials exceed the performance of most other materials. This review highlights developments in synthesis methods and mechanisms and gives an overview of the state of the art morphologies, particle sizes, and optical properties of YAG:Ce on the nanoscale.

“…10)15) Although the preparation process of Nd: YAG powders is simple and the powder is easy to produce by the traditional solid-phase reaction method, impurities will inevitably be introduced in the ball grinding process, and the uniformity of prepared powder is poor, which will affect the subsequent sintering process, resulting in a large number of scattering losses and severely reducing the transmittance of the final ceramic. 16) In comparison, the Nd: YAG powders prepared by wet chemical method, such as coprecipitation, 17)19) homogeneous co-precipitation, 20), 21) solgel, 22)24) spray pyrolysis, 25) hydrothermal, 26),27) and combustion synthesis 28), 29) has better uniformity.…”

Nd 3x Y 3¹3x Al 5 O 12 (Nd:YAG) powders with high uniformity were synthesized by reverse-titration co-precipitation method. The precipitation formation process and dispersion mechanism of Nd:YAG precursor in coprecipitation process were analyzed, and the influence of the preparation technology on the dispersion of powders was explored by adjusting the concentration of precipitator, alcohol-water solvent and ratio of composite dispersant. In addition, through the analysis of the precursor calcination process, combined with SEM and particle size analysis, it is shown that, under optimum processing conditions, the powders have excellent particle uniformity, narrow particle size distribution and appropriate crystal size when calcined at 1150°C for 2 h.

Yttrium aluminum garnet (YAG, Y3Al5O12) nanoparticles were synthesized by ultrasound-assisted and ultrasound-microwave-assisted alkoxide hydrolysis precipitation methods. The effect of reaction parameters including pH value, ultrasonic radiation time, and calcination temperature on the composition of the products was investigated. The YAG nanoparticles and their precursor were characterized by X-ray powder diffraction (XRD), differential thermal analysis (DTA), Fourier-transform infrared spectroscopy (FT-IR), and high-resolution transmission electron microscopy (HRTEM). The results show that the single ultrasound-assisted method to synthesize YAG phase often contains intermediate phases of YAM (Y4Al2O9) and YAP (YAlO3); pure YAG phase can form only at special conditions and as single crystal. The pure phase YAG powders can be obtained at each experimental condition when using ultrasound-microwave-assisted synthesis and the grain is polycrystalline. This is due to the microwave radiation which promotes atomic diffusion and forms a lot of crystal nuclei of YAG in the precursor. The YAG nanoparticles with a grain size of 18 nm can be obtained at a calcination temperature of 900°C when using ultrasound-microwave-assisted method.
