“…The process is quite different from the solid reaction method [21,22]. This result is in accordance with the appearance of the FTIR peaks corresponding to metal-oxygen vibrations, and is further proof of the crystallization of YAG at 850 • C. The crystallization temperature is comparable to the lowest ones reached using the co-precipitation and sol-gel methods [13,23]. As is well known, a second phase, especially hexagonal YAlO 3 (h-YAlO 3 ), often appears in the products of YAG synthesis using the co-precipitation method [24], because of the non-homogeneous composition of the YAG precursor.…”

“…YAG powders was traditionally produced via solid state reaction [10] by milling the component oxides under repeated mechanical mixing and require extensive heat (\1400°C) to eliminate the intermediate phases of YAG. To overcome this various methods like co-precipitation [11][12][13][14][15], Hydrothermal synthesis [16,17], sol-gel process [18,19], Spray pyrolysis [20,21] and Combustion synthesis [22,23] was adopted. It is recognized that wet chemical processing of multi-cation oxides provides considerable advantages like molecular level mixing; less effort more powder yield and excellent homogeneity of the final product [24].…”

Rare-earth doped YAG nanopowders are widely used as luminescence material because of its technological importance in opto-electronic applications especially for solid state lasers. In this work, YAG and Yb:YAG were prepared by co-precipitation method. The thermal behavior was investigated by differential thermal analysis and thermo gravimetric analysis. The phase formation, elemental analysis, particle size distribution, optical absorbance, fluorescence behavior and morphology of YAG and Yb:YAG nanopowder were analyzed through powder X-ray diffraction technique, energy dispersive X-ray analysis, dynamic light scattering, UV-Vis, photoluminescence spectroscopy, high resolution scanning electron microscopy, high resolution transmission electron spectroscopy respectively. From the optical study, Yb:YAG gives optical absorption at 975 nm and predominant infrared emission at 1030 nm.

High-quality neodymium-doped yttrium aluminum garnet (Nd:YAG) transparent ceramic (4.0 mole percent) was fabricated by a solid-state reaction method and vacuum sintering. The microstructure, optical transmittance, spectral properties and laser performance were investigated. The average grain size of the sample is about 10 mm. The transmittance of a 2.8-mm thick sample reaches 79.5% at the laser wavelength of 1064 nm. The highest absorption peak is centered at 807 nm and the absorption coefficient is 13.9 cm 21 . The absorption coefficient at the laser wavelength is 0.2 cm 21 . The main emission peak is at 1064 nm and the fluorescence lifetime is 102 ms. A laser diode (808 nm) whose maximum output is about 1000 mW was used as a pump source and an endpumped laser experiment was performed. The 1064 nm-CW-laser output was obtained and the threshold is 733 mW. With 998 mW of maximum absorbed pump power, a laser output of 17 mW is obtained with a slope efficiency of 6.1%.
