Notes:
We have studied the effect of unsaturated-polyester and epoxy hosts on the volume phase holographic recording properties of media using camphorquinone and 2, 3-pentanedione as guests. The sensitivity, determined by holographic diffraction efficiency on exposure to an Ar+ laser, was used as a probe for the chemical behavior of the medium. Intramolecular, photochemical reactions involving 2, 3-pentanedione in the epoxy hosts are less effective than in the polyesters. For inter-molecular reactions initiated by photoexcited camphorquinone, media having polyester hosts are again more sensitive. The availability in unsaturated-polyester hosts of residual monomer for free-radical addition reactions is a determining factor in the recording mechanism.
