| titleOfInvention | Single crystalline essentially cubic hafnium, zirconium pyrophosphate luminescent material having improved brightness |
| abstract | ABSTRACT OF THE DISCLOSURE A mixture of starting materials, corresponding to an oxide composition within an area of the ternary diagram for (Hf, Zr)O2, A2O, P2O5 formed by connecting points defined by the molar com-positions: 49 (Hf,Zr)O2 - 1 A2O - 50 P2O5; 15 (Hf,Zr)O2 - 35 A2O - 50 P2O5; and 15 (Hf,Zr)O2 - 1 A2O - 84 P2O5, reacts to form large single crystalline essentially cubic particles of (Hf1-xZrx) P2O7 luminescent material, and an aqueous - soluble second phase removable by washing. The large single crystalline particles show improved emission intensity (brightness) upon x-ray excitation. Use of the material in an x-ray intensifying screen results in improved resolution of an exposed image on x-ray film. |
