Confining energy migration in upconversion nanoparticles towards deep ultraviolet lasing

A general approach to maximize upconversion luminescence in stoichiometric lanthanide lattices is lacking. Here, Chen et al. report a NaYbF4:Tm lattice and demonstrate fine-tuning of energy migration by controlling dimensions of the crystal lattice, highlighting their potential for deep ultraviolet...

Sumario:A general approach to maximize upconversion luminescence in stoichiometric lanthanide lattices is lacking. Here, Chen et al. report a NaYbF4:Tm lattice and demonstrate fine-tuning of energy migration by controlling dimensions of the crystal lattice, highlighting their potential for deep ultraviolet lasing.
