Confining energy migration in upconversion nanoparticles towards deep ultraviolet lasing

Manipulating particle size is a powerful means of creating unprecedented optical properties in metals and semiconductors. Here we report an insulator system composed of NaYbF(4):Tm in which size effect can be harnessed to enhance multiphoton upconversion. Our mechanistic investigations suggest that...
