Figure 3From: A facile hydrothermal approach to the synthesis of nanoscale rare earth hydroxides TEM images of La(OH) 3 nanorods. Prepared under different reaction times and water/ethanol volume ratios: (a-d) 6, 12, 18, and 24 h while DDA volume and water/ethanol volume ratio are fixed at 5 mL and 1/1, respectively; (e-h) water/ethanol volume ratio of 100/0, 80/20, 20/80, and 0/100 while DDA and reaction time are fixed at 5 mL and 18 h, respectively.Back to article page
