    Abstract

    <p num="37">FIELD: chemistry.</p> <p num="38">SUBSTANCE: invention relates to inorganic chemistry and indicator equipment and can be used in making plasma panels excited by a constant and variable field. Red-radiating photoluminescent phosphor, which is a borate of composition Sr<sub>3</sub>Bi<sub>2</sub>(BO<sub>3</sub>)<sub>4</sub>:Eu<sup>3+</sup>, obtained by crystallisation from melt. Luminophore crystalline structure consists of isolated triangular radicals BO<sub>3</sub>, and in crystallographically nonequivalent cationic positions M1, M2 and M3 there are Sr and Bi atoms. Position M1 is coordinated with eight oxygen atoms and is populated by approximately 80 % Sr and 20 % Bi. Position M2 is surrounded by eight oxygen atoms and is populated by approximately 60 % Sr and 40 % Bi. Polyhedron M3 is an eight-vertex and this position is populated by approximately 80 % Bi and 20 % Sr.</p> <p num="39">EFFECT: invention allows to increase optimal concentration of europium in luminophore and to use in its compo
