Efficient luminescence from zeolites


  • The authors wish to express their gratitude to Dr. C. R. Ronda and D. Waedow for their invaluable contributions to discussions and experiments in this investigation.


Zeolites as potential luminescent materials is a subject that has received little attention previously. The optical properties–UV emission and reflectance/absorbance spectra–of zeolites X and Y prepared with various degrees of Ce doping are described and an interpretation of the results is proposed based on the occupation of the various zeolitic coordination sites (see Figure).
