Abstract

Through the strategic application of upconversion rare-earth nanoparticles (UCNPs), this work has reduced the intensity of the traditional super-resolution by 2-3 orders of magnitude. It reveals a new mechanism of stimulated emission caused by the photon avalanche effect. With only 30mW continuous laser, resolution down to 28nm has been attained, which is only 1/36 of the excitation wavelength.
