Photoluminescence properties of a novel phosphor CaB2O4:Eu3+ under NUV excitation.
The new borate phosphor CaB(2)O(4):Eu(3+) was synthesized by solid-state method and their photoluminescence properties were investigated. The results show that the pure phase of CaB(2)O(4) could be available at 900 degrees C, CaB(2)O(4):Eu(3+) phosphor could be effectively excited by the near ultraviolet light (NUV) (392 nm), and the luminescent intensity of CaB(2)O(4):Eu(3+) phosphor reached to the highest when the doped-Eu(3+) content was 4 mol%. The emission spectra of CaB(2)O(4):Eu(3+) phosphor could exhibit red emission at 612 nm and orange emission at 588 nm, which are ascribed to the (5)D(0)-(7)F(2) and (5)D(0)-(7)F(1) transitions of Eu(3+) ions.
