| 20080296503 | HIGH ENERGY RESOLUTION SCINTILLATORS HAVING HIGH LIGHT OUTPUT - A scintillator composition includes a matrix material, where the matrix material includes an alkaline earth metal and a lanthanide halide. The scintillator composition further includes an activator ion, where the activator ion is a trivalent ion. In one embodiment, the scintillator composition includes a matrix material represented by A | 12-04-2008 |
| 20090146065 | SCINTILLATOR MATERIALS BASED ON LANTHANIDE SILICATES OR LANTHANIDE PHOSPHATES, AND RELATED METHODS AND ARTICLES - A scintillator composition is described. The composition includes a matrix material in the form of a host lattice characterized by a 4f5d→4f optical transition under activation. The matrix material is based on certain lithium-lanthanide silicate compounds or alkali-lanthanide phosphate compounds. The composition also includes a praseodymium (Pr) activator for the matrix material. Radiation detectors which include crystal scintillators are also part of the present invention, as are methods for detecting high-energy radiation, using these devices. | 06-11-2009 |
