ABSTRACT |
Spectral properties of europium activated intermediate compounds in the system R2O3-P2O5(R=La, Y, and Gd) are presented, including also phosphors with bismuth and vanadate sensitization. The sensitized phosphors are less efficient than unsensitized phosphors. (The ratio of oxygen to phosphorus effects the charge transfer band) Most phosphors have low efficiencies, but La3PO7 and Gd3PO7 hosts are possible for commercial luminescent materials. |
