Low threshold lasing emissions from a single upconversion nanocrystal
Cross-relaxation between neighbouring emitters usually limits the brightness of luminescence due to self-quenching. Here, the authors present single upconversion nanoparticle lasing where the cross relaxation modulates the brightness and ultra-low threshold lasing is achieved.
