Abstract

A blue-emitting phosphor - Ca₂BN₂F:Eu²⁺ was synthesized by a solid state reaction. Ca₂BN₂F crystallizes in the orthorhombic system with space group Pnma (No. 62) and Z = 4. The Ca₂BN₂F:Eu²⁺ exhibites broad emission and excitation bands corresponding to the allowed f→d electronic transition of Eu²⁺. Concentration quenching of Eu²⁺ emission was observed for 1 mol% due to the energy transfer between Eu²⁺ ions via electric multipolar interaction with the critical transfer distance of about 25.11 Å. In addition, the thermal stability and applications of blue-emitting Ca₂BN₂F:Eu²⁺ phosphors in n-UV LED have been firstly discussed in this study. The preliminary data demonstrate that the novel blue-emitting phosphor exhibits the potential to be an n-UV convertible phosphor.
