In the recent past, numerous attemps have been untertaken to utilize nano-meso- and microporous materials as hosts for luminescent guest species. The accessible spectral range now spreads from the vacuum ultraviolet to the near infrared (NIR), if sodalites are included in this scope. Although borderline materials in this context with respect to pore sizes, examples of the sodalites' versatility in accomodating small but efficient luminescent entitites are discussed. In particular, optical materials, whose spectral range of operation is allocated in the NIR, have recently attracted our attention and will form the focus of this report. We would like to express our gratitude to the German BMB+F (Grant 03N8019F) for financial support of part of this research (M.L.).
