Nanostructured Nd:YAG powders via gel combustion: The influence of citrate-to-nitrate ratio

Solvothermal nanoYAG synthesis: Mechanism and particle growth kinetics

“…The degree of crystallinity and phase(s) present were determined using an X-ray diffractometer (Bruker D8, Bruker AXS GmbH, Karlsruhe, Germany) at a step size of 0.02° from 20° to 90° 2θ. The average crystallite size was calculated from the line broadening of (321), (400), (420), (422), (431) and (521) reflections using the Scherrer formula reported elsewhere [8,10].…”

“…Routes such as sol-gel [6,7], co-precipitation [6,8], and combustion synthesis [9,10], often produce single phase YAG powders, but with a high degree of agglomeration.…”

Co-precipitation Synthesis and Spectroscopic Studies of YAG and Yb:YAG Nanopowder for Opto-Electronic Applications

“…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].…”

Solid-state-reaction fabrication and properties of a high-doping Nd:YAG transparent laser ceramic

“…With rapid enhancement in laser output power and efficiency, laser ceramics have become one of the hottest research fields in the 21st century and many countries focus manpower, material and financial resources on it. A number of research institutes in China have achieved some useful results on laser ceramics [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] and laser output has also been obtained [20][21][22].…”
