Information × Registration Number 0213U004029, 0112U002939 , R & D reports Title Development of nanodisperse cathodophosphores based on virtual perovskite ferroelectrics popup.stage_title Head Svechnikov Sergey Vasil'evich, Registration Date 04-02-2013 Organization Institute of Semiconductor Physics of National Academy of Sciences of Ukrain popup.description2 The nanodispersed powders SrTiO3:Pr3+,Al and SrTiO3: Pr3+, Fe were prepared; the experimental study of elemental composition of initial material was carried out, the EPR measurment of phosphors, photoluminescence, cathodoluminescence and theoretical studies were carried out , in which: (a) experimentally determined that one of the initial material, ethanol, contains active impurity Fe, which influence on the photo and cathodoluminescence of phosphors, (b) it was found that the addition of Fe in the amount of 5 10-5 mol.%. increases brightness cathodoluminescence in 10 times, (c) optical properties of crystal SrTiO3: Pr3 +, Al, that was investigated, permit to convert UV radiation into visible. (d) a strong relation between the structural distortion, polarization and magnetization in nanosystems MxSr1-xTiO3 was established, which opens up the potential use them as multiferroelectrics.
