摘要：
A reflection type volume‐phase hologram was recorded on poly(vinylcarbazole) (PVCz) in the presence of CI4. The grating with a half‐height width of 19nm was made with an argon ion laser at 488nm or 514. 5nm. The sections of PVCz and a dichromated gelatin (DCG) hologram, responsible for the diffraction efficiency, were observed by scanning electron micrography (SEM) and transmission electron micrography (TEM). Those micrographs showed that the amplitude of the index modulation in the hologram is formed bý voids. The diffraction efficiency was simulated with the parameters observed by TEM and showed that a thin PVCz hologram film attains the same diffraction efficiency as the thick DCG sample, because of the large refractive index of PVCz.
