A FACILE SYNTHESIS OF NANO-SIZED ND:YAG POWDERS BY BUBBLING AMMONIA
https://doi.org/10.17073/1683-4518-2014-6-52-56
Abstract
A facile way for the co-precipitation synthesis of nano-sized Nd3+-doped yttrium aluminum garnet (Nd:YAG) powders has been developed through bubbling ammonia technique. A variety of techniques, such as thermogravimetry/differential scanning calorimetry, X-ray powder diffraction, Fourier transform infrared spectra and scanning electron microscopy were adopted to characterize the resulting samples. The results showed that stoichiometric Nd:YAG powders could be derived by calcinating the precursor at 900 °C for 2 h. Furthermore, lower ammonia flow rates (5-10 ml/min) was favorable for the formation of well-defined Nd:YAG powders with a mean particle size of ~70 nm. The approach reported here does not utilize the commonly used manual titration for synthesizing multibasic oxides, making it industrially more feasible. Ill. 6. Ref. 26.
