Ytterbium monosilicate (Yb2SiO5) were synthesized by cocurrent coprecipitation method. The precursors were prepared by the hydrolysis and the formation of TEOS with embedding Yb atoms under alkali-catalysis, and then calcined to obtain Yb2SiO5 powders. The effect of the system pH value on the synthesis process of Yb2SiO5 powders was investigated. The results reveal that the system pH value did not significantly influence the crys-talline phase of Yb2SiO5 nanoparticles. However, it is sensitive to the grain size, crystallization temperature and phase transition temperature of Yb2SiO5. The polym...
