Dichromated gelatin films present sensitivity to red light without any special sensitization. This sensitivity is due to an absorption appearing in dichromated gelatin films and attributed mainly to a charge–transfer transition which results in an electron transfer from gelatin to chromium. To characterize holographically this recording material, both reflection and transmission gratings have been obtained using the 632.8-nm radiation from a He–Ne laser.
