Abstract: Abstract Currently, concentration-induced near-infrared upconversion quenching at highly doped levels of lanthanide ions poses a significant constraint for their practical applications. In this work, the fabricated Tm3+/Yb3+ codoped Na0.5Bi2.5Nb2O9 (NBN) materials with a layered structure… read more here.

Abstract: Luminescence nanomaterial-based lateral flow assay (LFA) is promising for point-of-care tests. However, the detection sensitivity and accuracy are often affected by the interferences of autofluorescence and photon scattering from nitrocellulose membrane and colored plasma. Here,… read more here.
