Figure 4From: (Zn,H)-codoped copper oxide nanoparticles via pulsed laser ablation on Cu-Zn alloy in waterTEM BFI (left) and corresponding SAED pattern (right). (a) Poorly crystallized condensates prepared by PLA in water and then dwelled in water for 1 day and (b) randomly oriented metallic α-phase and W-ZnO nanocrystals newly crystallized from the amorphous phase upon electron irradiation for 20 min.Back to article page
