Holographic Storage Characteristics of PQ/poly(methyl methacrylate) have been significantly improved by
doping metallic ion Yb+3 and Er+3. The hybrid materials display significant enhancement in the holographic
characteristics. The diffraction efficiency promote to 59% with Yb+3, to 47% with Er+3 from the undoped sample
is 40%. The increment is up to 47% in Yb+3 sample; the dynamic range enhance to 2.12 and 1.58 on Yb+3 and
Er+3 containing sample individually in comparison to 1.16 for the undoped copolymer. The increment of
dynamic range is up to 82% for Yb+3 containing sample. The related mechanism of these changes is preliminary
discussed with the analysis of UV-vis, FT-IR and Photoluminescence spectroscopy.
