Commentaar:
The outermost portion of the samples are generally not luminescent.
Eucryptite is sostructural with Phenakite and willemite. The Al and Si atoms of eucryptite are disordered in the sites equivalent to the Be and Zn in phenakite and willemite and the Li atoms of eucryptite occupy the sites equivalent to the Si positions in phenakite and willemite.
