TEM BFI, SAED, and corresponding EDX of the as-formed PLA sample. (a) Nanocondensates of (Zn,H)-codoped cuprite (Cu2O) and metallic α-phase in random orientation and (b) submicron-sized Cu particulate slightly dissolved with Zn and co-existing nanoparticles of metallic α-phase and W-ZnO with corresponding point-count EDX analysis at X and Y positions, respectively. Note that W-ZnO in (b) was mainly crystallized from an amorphous matrix upon electron irradiation for 10 min. The Ni counts are from the sample supporting the nickel grid.
