| titleOfInvention | Method for producing metal fluoride single crystal |
| abstract | PROBLEM TO BE SOLVED: To provide a method for easily producing a single crystal having little absorption in a vacuum ultraviolet light region with good reproducibility in a method for producing a metal fluoride single crystal by a melt solidification method such as Czochralski method. To do. [MEANS FOR SOLVING PROBLEMS] Before starting crystal growth by bringing a seed crystal into contact with a raw material metal fluoride melt, after melting the raw material metal fluoride in an inert gas and / or fluorine-based gas atmosphere, The raw material is solidified and the system is evacuated. By performing melting of the raw material metal fluoride for bringing the seed crystal into contact after performing this operation, a single crystal having very little absorption around 140 to 170 nm can be produced with good reproducibility. Contact of the seed crystal and crystal growth are also performed in an inert gas and / or fluorine-based gas atmosphere. [Selection] Figure 3 |
