摘要：

Highly resolved fluorescent patterns are generated in an individual silver-exchanged K-A zeolite crystal using two-photon excitation (see figure). The high stability, brightness, and spatial resolution of the patterns are an important advantage over the current state-of-the-art techniques in optical encoding of microcarriers. Therefore, this material shows high potential as a quality and/or safety label to prevent counterfeiting or as an advanced biolabel.
