Eu (3 +) And Tb (3 +) And Ce (3 +) Ion Activation Babo, Cboc, Mao, Zbo Base Of New Luminescent Materials

The host BABO(BaAl₂B₂O₇), CBOC(Ca₂B₅O₉Cl), MAO(MgAl₂O₄), ZBO were activated by Eu³⁺,Tb³⁺, Ce³⁺ et al rare earth ions. A serious of luminescent materials was prepared with Flash Combustion Method, Hydrothermal Method of Soft Chemistry and High Temperature Solid Method. Luminescent materials of CBOC: Eu, BaAl₂B₂O₇: Eu³⁺, MAO: Ce³⁺/Tb³⁺, ZBO: Eu³⁺/Tb³⁺ were gained. Effect of excitation conditions, rare earth ions concentration of activated and sensitized reagent, flux, temperature on spectral properties and microcosmic structure were studied; The energy transfer mechanism of Eu³⁺â†'Eu³⁺, Tb³⁺â†'Eu³⁺, Ce³⁺â†'Eu³⁺ in BABO, CBOC, MAO were studied; Microcosmic photographs were observed with SEM; Functional action of rare earth oxide and luminescent powder in the glass fibers were also discussed. Luminescent glass fibers were prepared by Tb₄O₇, Ca₃B₇O₁₃Cl: Eu³⁺, Zn₄B₆O₁₃: Ce³⁺/Tb³⁺, MgAl₂O₄: Ce³⁺/Tb³⁺, SrAl₂O₄: Eu³⁺/Dy³⁺, SrAl₂O₄: Dy³⁺ added to host B₂O₃-SiO₂-ZnO-SrO-CdO.
