| abstract |
The present invention provides a short wavelength light emitting device such as an ultraviolet light emitting device or a blue light emitting device in a container having a window provided with a window panel formed of calcium fluoride crystals. According to the present invention, a light emitting device having high reliability can be obtained. The fluoride crystal of the present invention contains either or both of a metal or a metal halide. In the method for producing a fluoride crystal of the present invention, in the method for producing a fluoride crystal in which a raw material powder is filled in a cavity of a crucible and the crucible is heated in a vertical bridgeman furnace, the cross section of the pupil part of the crucible has the shortest diameter. This is a small thing. In the crucible of the present invention, in order to produce fluoride crystals, a raw material powder is filled in the cavity, and the crucible is heated in a vertical bridgeman furnace, where the cross section of the cavity is small in diameter. |
