crystal immobilized on a cover glass in Ar-saturated methanol solu-
tion containing DN-BODIPY under a 488-nm laser and UV irradiation. The blue and red dots in the transmis-
sion image indicate the location of luorescence bursts on the {001} and {101} facets of the crystal, respectively,
observed during 3-min irradiation. (Adapted with permission from Tachikawa, T., Yamashita, S., Majima, T.,
