Luminescence property improvement of Ba2LaSbO6:Mn4+ phosphor by using Dy3+ or H3BO3
Abstract
Ba2LaSbO6:Mn4+, Ba2LaSbO6:Mn4+, Dy3+, and Ba2LaSbO6:Mn4+, H3BO3 phosphors are synthesized in the air by high temperature solid state reaction method. The particle sizes and sintering degree of Ba2LaSbO6:Mn4+ phosphor may be changed by doping Dy3+ ion and H3BO3. When the small amount of Dy3+ ion and H3BO3 are codoped, the emission intensity of Ba2LaSbO6:Mn4+ phosphor can be enhanced 1.2-1.3 times and the quantum efficiency of Ba2LaSbO6:Mn4+ phosphor can be improved. The lifetime of Ba2LaSbO6:Mn4+ phosphor may be changed by doping Dy3+ ion and H3BO3. The experimental results are valuable in research of luminescence property of Mn4+-doped luminescence materials.
