Cerium doped crystals
A crystal having good optical transmission between 260 nm and 280 nm and strongly absorbing at 285 nm and higher, which is nonhydroscopic and stable at temperatures to 250° C. An example of such a crystal is Cerium doped YLiF4. These properties make YLiF4 crystals doped with Ce3+ excellent materials...

Zusammenfassung: | A crystal having good optical transmission between 260 nm and 280 nm and strongly absorbing at 285 nm and higher, which is nonhydroscopic and stable at temperatures to 250° C. An example of such a crystal is Cerium doped YLiF4. These properties make YLiF4 crystals doped with Ce3+ excellent materials for use as UV filters in the missile early warning spectral band. Optical devices including missile detection systems are also provided. |
