ABSTRACT
In order to gain a better understanding of the interfacial alloying in binary immiscible metallic mutilayers, we established a size-dependent kinetic model to address the diffusion that takes place at the interface in the immiscible metallic bilayer on nanoscale, and found an abnormal interfacial diffusion behavior when the diffusion length less than 2 nm. The nanosize-dependent diffusion coefficients of binary immiscible metals in bilayers were predicted on the basis of the proposed model. Taking the Cu–Ta multilayers as an example, we showed that these theoretical predictions are in agreement with experiments and computational simulations.

    Ce3+ doping of Y2O2S:Er3+ can be used to suppress the visible anti-Stokes luminescence of the phosphor under excitation in the range 0.90–0.98 µm. We take advantage of this effect to create a new, efficient “invisible” IR phosphor emitting in the range 1.5–1.6 µm.
