Synthesis of nano-scaled yttrium aluminum garnet phosphor by co-precipitation method with HMDS treatment

Synthesis of yttrium aluminum garnet (YAG) powder by homogeneous precipitation combined with supercritical carbon dioxide or ethanol fluid drying

“…7a and b, respectively, is probably due to the combustion of decomposed residual ethanol. 46 Because no weight loss is detected, the exothermic peaks at 963 • C in Fig. 7a and 935 • C in Fig.…”

High luminance YAG:Ce nanoparticles fabricated from urea added aqueous precursor by flame process

“…processes, YAG:Ce can be prepared by sol-gel [1,10], glycothermal [8], precipitation [11,12], and polymer [13]. From these processes, typically amorphous particles were produced in the first step of preparation.…”

Influence of pH values on (Nd+Y):Al molar ratio of Nd:YAG nanopowders and preparation of transparent ceramics

“…According to this, the calcining temperature should be above 1029.5 • C. In this paper, a calcining temperature of 1050 • C was chosen to obtain the nanopowders with a pure YAG phase and high sintering activity. The Nd:YAG precursors are carbonate and hydroxide mixed precipitates, and the partial Al hydroxide dissolved as Al(OH) 4− ions at pH value above its isoelectric point range of ∼8.5-9.5 in the slurries, while the isoelectric points of Y hydroxide is between 10.5 and 11.5 [18]. This conclusion indicates that it is impossible to guarantee the complete precipitation of Y, Al and Nd at the same pH value during the preparation process of Nd:YAG precursors.…”
