Synthesis of La3+ and Nd3+ co-Doped Yttria Nanopowder by Sol-Gel Combustion Method

In this research, the nanopowders of lanthanum and neodymium co-doped yttria were synthesized by sol-gel combustion method. Citric acid and glycine were used as the gel maker and fuel respectively. The effect of molar ratio of citric acid to glycine on the grain size and morphology was evaluated. Th...
