Luminescence property improvement of Ba2LaSbO6:Mn4+ phosphor by using Dy3+ or H3BO3

Ba 2 LaSbO 6 :Mn 4+ , Ba 2 LaSbO 6 :Mn 4+ , Dy 3+ , and Ba 2 LaSbO 6 :Mn 4+ , H 3 BO 3 phosphors are synthesized in the air by high temperature solid state reaction method. The particle sizes and sintering degree of Ba 2 LaSbO 6 :Mn 4+ phosphor may be changed by doping Dy 3+ ion and H 3 BO 3 . When the small amount of Dy 3+ ion and H 3 BO 3 are codoped, the emission intensity of Ba 2 LaSbO 6 :Mn 4+ phosphor can be enhanced 1.2–1.3 times and the quantum efficiency of Ba 2 LaSbO 6 :Mn 4+ phosphor can be improved. The lifetime of Ba 2 LaSbO 6 :Mn 4+ phosphor may be changed by doping Dy 3+ ion and H 3 BO 3 . The experimental results are valuable in research of luminescence property of Mn 4+ -doped luminescence materials.
