- •
The luminescence switching is controlled by temperature and pulse duration.
- •
The mechanism based on the multi-phonon-assisted excitations is proposed.
- •
Blue luminescence under short-pulse excitation originates from the surface ions.
- •
Temperature has a big effect on luminescence color output.
