    Concentration Quenching of Tb3+ Doped SiC:H and AlN Thin Films in Photoluminescence and Cathodoluminescence Measurements

    We present a systematic study of photo- and cathodoluminescence measurements in the visible of Terbium doped SiC:H and AlN thin films. The Terbium atomic concentrations vary from 0.9 to 10% for the SiC:H and f...

    The Structure of Antigen-Antibody Layers Adsorbed on Silica Surfaces: a Scanning Angle Reflectometry Study

    Scanning Angle Reflectometry (SAR) is used to investigate the structure of protein layers deposited sequentially, first the antigen and then the antibody, on a silica surface. The reflectivity curves are analy...
