NARROWBAND ULTRAVIOLET B EMISSION FROM GADOLINIUM AND PRASEODYMIUM CO-ACTIVATED CALCIUM PHOSPHATE PHOSPHORS FOR PHOTOTHERAPY LAMPS
Different phases of calcium phosphates co-doped with gadolinium and praseodymium were prepared by co-precipitation, urea combustion, citrate-gel combustion and microwave-assisted methods. Ca5(PO4)3OH:Gd3+,Pr3+ phosphors were prepared by the co-precipitation and citrate-gel methods, and were characte...
