A green phosphor Ba2Ca(BOa)2:Eu2+ was syntheMzed by a high temperature solid-state reaction method under a reductive amosphere,, The luminescence and site occupancy of Eu2+ in Ba2Ca(BOa)2 are investigated. Ba...
The novel vacuum ultraviolet (VUV) excited Na3 Y9O3 (BO3)8:Tb^3+ (NYOB:Tb^3+) green phosphor is prepared. Strong VUV photoluminescence and high quenching concentration of Tb^3+ (20 wt%) are observed in N...
Ca3Y2 (BO3)4:Eu^3+ phosphor is synthesized by high temperature solid-state reaction method, and the Iuminescence characteristics are investigated. The emission spectrum exhibits two strong red emissions at 613 and...
