Information × Registration Number 0211U005959, 0111U004021 , R & D reports Title Development of nanodisperse cathodophosphores based on virtual perovskite ferroelectrics popup.stage_title Head Svechnikov Sergey Vasil'evich, Registration Date 12-01-2012 Organization Institute of Semiconductor Physics of National Academy of Sciences of Ukrain popup.description2 The nanosized SrTiO3 doped with Pr3+ and Al was obtained. Experimental investigations of their structure, photoluminescence, cathodoluminescence and theoretical investigations were carried out, which resulted in: (a) the influence of size effects, diffusion, electromigration and surface segregation of oxygen vacancies in nanosized SrTiO3 on its local electromechanical response was established; (b) the influence of concentration and spatial distribution of defects on the polar and magnetic properties of incipient nanosized ferroelectrics was established; (c) the influence of the impurities of Al on the crystal structure was found; (d) the dependence of photo-and cathodoluminescence depending on the concentration of Pr3+ and Al was found; (e) the concentration of Pr3+, which provides high brightness of the luminescence, was determinated.
