    Luminescent properties of Y2SiO5:Ce thin films 

    Coetsee, Elizabeth (University of the Free State, 2010-05)
    The luminescent properties of yttrium silicate doped with cerium (Y2SiO5:Ce) phosphor thin films were investigated. A detailed investigation (cathodoluminescence (CL), photoluminescence (PL) and Gaussian peak fits) was ...
