Abstract
Disclosed herein are material compositions that include a metal doped, alumina rich yttrium aluminum garnet (YAG:M). Also provided according to embodiments of the invention are scintillator compositions that include Y3-xMxAl5+yO12+z, as a primary phosphor and wherein 0≦x<0.03, 0.001<y<0.2 and 0≦z<0.012, or 0≦x<0.01, 0.001<y<0.1 and 0≦z<0.0625 and M comprises elements selected from cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), Chromium (Cr) and lutetium (Lu). and can include a single or a mixture of a these elements.
Claims7
A luminescent inorganic material comprising Y3-xMxAl5+yO12+z, wherein 0≦x<0.03, 0.001<y<0.2 and 0<z<0.012 and M is selected from, cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), Chromium (Cr) and lutetium (Lu) or combinations thereof.
A method of forming a luminescent inorganic material comprising:
- (a) providing a mixture of Y2O3, and Al2O3 in a Y:Al molar ratio of between 1.5:2.5 and 1.5:2.75;
- (b) heating the mixture to a liquid state;
- and
- (c) solidifying the mixture to form the compound.
