Preparation and photocatalytic properties of hexagonal-shaped ZnO:Sm3+ by microwave-assisted hydrothermal method

Novel 3D rods ZnO:Sm monophasic microcrystals have been synthesized by the microwave-assisted hydrothermal (MAH) method at 140 °C for 10 min. The experimental results revealed that concentration of samarium have a significant influence on the band gap and photocatalysis. On the other hand, the samar...
