Luminescence in nanostructured materials

Nanostructured Materials, 1995
Abstract Some new photoluminescence phenomena, which have not been observed for conventional coarse grain materials, are reported for nanostructured materials,such as nanostructured η,γ-Al 2 O 8 , boehmite, TiO 2 ( anatase), and amorphous silicon nitride.

Recording Holograms in Luminescent Materials

Applied Optics, 1969
The fluorescein-boric acid glass organophosphor has been characterized as a transient photochromic hologram receptor medium in which an excited electronic state gives rise to the holographic grating. It is shown that the holographic signal depends upon dye concentration, sample thickness, and writing laser power.

Designing Luminescent Materials

Advanced Materials, 1991
Review: Non‐conventional phosphor host materials such as cryptands (see Figure) or zeolites now offer potential alternatives to the traditional inorganic solid‐state materials which find applications in e.g. fluorescent lamps, T.V. sets, or X‐ray detectors.
