Photoluminescence of open-framework phosphates and germanates.
Upon excitation by long wavelength UV radiation, strong room temperature luminescence is observed in a family of metal-activator-free zeolite-type materials; the luminescent output from the large cage UCSB-8Mg structure is independent of temperature from 298 K until at least 77 K.
