Upconversion luminescence is an anti-Stokes' emission process by converting long wavelength near-infrared (NIR, 980 nm) irradiation into shorter wavelength visible light emission, which demonstrates many advantages including no autofluorescence, low damage to samples, no photobleaching, and high sensitivity. Based on the Rhodamine B thiolactone (RBT) functionalized NaYF(4):15%Yb(3+),5%Er(3+) (UCNPs@RBT) nanocomposites, an ultrasensitive, selective, and rapid upconversion luminescence resonance… Expand
