Abstract:
The invention provides borate phosphors composed of Ca1-xAlBO4:Mx, wherein M is Pr3+, Nd3+, Eu3+, Eu2+, Gd3+, Tb3+, Ce3+, Dy3+, Yb2+, Er3+, Sc3+, Mn2+, Zn2+, or combinations thereof, and 0≦x≦0.3. The invention also provides borate phosphors composed of Zn1-x-yB2O4:Eu3+x, Bi3+y, wherein 0≦x≦0.6 and 0≦y≦0.6. The borate phosphors emit visible light under the excitation of ultraviolet light or blue light, and may be further collocated with different colored phosphors to provide a white light illumination device.
