Paper Abstract

We have measured the spectroscopic properties of upconverting phosphors relevant to their use of in-vitro diagnostics and other application. These novel reporters have a number of useful properties for biological and medical applications, including no autofluorescent background, no photobleaching, excitation with inexpensive and compact cw diode laser sources, and narrow emission bands. Properties we have measured include the intensity dependence of the absolute phosphorescence power per phosphor particle, the intensity-dependent temporal response, and histograms of phosphorescence intensities on a single particle basis.
