While high-purity hexagonal boron nitride monocrystal (hBN) obtained by way of a high temperature/high-pressure treatment in the presence of a high-purity solvent has excellent properties in terms of far-UV luminescence characteristics, it has drawbacks including that it can be easily adversely affected by mechanical vibrations and impetus, that monocrystal shows a poor morphological retentiveness and that the luminescence characteristics fluctuate to shift the selected and set wavelength. The present invention can overcome the drawbacks of being easily affected by vibrations and showing a poor morphological retentiveness by grinding down the monocrystal obtained by a solvent/refining process into powder and applying the powder to a light emitting surface. Thus, the present invention provides crystal powder to be used for a far-UV luminescence device showing excellent luminescence characteristics that are stable and do not fluctuate.

An object of the present invention is to provide a composition which is excellent in safety and capable of dispersing uniformly on the mucous tissue when topically administered to mammals, and an ophthalmic solution comprising the composition and capable of stabilizing the tear film and keeping the tear film on the eyeball surface smooth. In a composition comprising a polysaccharide, particularly agar, and water as essential components, an ophthalmic solution comprising the agar-containing composition of which an amount of precipitated agar after performing centrifugal separation at with 40,000 ×g is less than 65 wt % of a total agar content has an excellent tear film stabilizing effect which was proved by a test on changes of corneal surface irregularity. Therefore, the agar-containing ophthalmic solution of the present invention has the effect of stabilizing the tear film on the eyeball surface over a prolonged period of time and is usable as an artificial tear fluid.
