文摘
- •
ZnO NCs were prepared by etching Zn sheets and annealing in ambient air at 200–400 °C.
- •
No monotonic change of crystal lattice parameters vs annealing temperature is revealed.
- •
The correlation between varying the FE emission peak and XRD parameters is detected.
- •
Donor-acceptor pair (DAP) nature of orange, yellow and green defects is confirmed.
- •
The types of shallow donors and deep acceptors in DAPs have been discussed.
