The right bright light: Silver‐exchanged zeolite 3A crystals show remarkable luminescent properties. Upon irradiation with high‐power UV light, a strong photoactivation process takes place which results in an emission increase of up to two orders of magnitude (see picture). The crystals of interest—or even small domains within one crystal—can be selectively activated by using a confocal microscope.
