| 摘 要： | Holographic parameters and photobleaching kinetics of the photopolymers with five different amine photoinitia-tors are studied. The maximum values of diffraction efficiency, photobleaching coefficient and quantum yield follow the sequence:Triethanolamine (TEA)> Diethanolamine (DEA)> Ethanolamine (EA)> Triethylamine (TETN)> Diethy-lamine (DETN). The holographic capabilities of photopolymer performances are determined by the number of functional groups in the amine molecular structure. There is an optimum proportion of the photoinitiator, the photosensitizer and the monomer in the test of holographic parameters with different amine concentrations. The maximum diffraction efficiency is 59.26%, sensitivity is 1.72 × 10 3 cm2/mJ, and the maximum refractive modulation index is 4.64×10 4.

| Abstract: | Holographic parameters and photobleaching kinetics of the
photopolymers with five different amine photoinitiators are studied.
The maximum values of diffraction efficiency, photobleaching
coefficient and quantum yield follow the sequence: Triethanolamine
(TEA)> Diethanolamine (DEA)> Ethanolamine (EA)> Triethylamine
(TETN)> Diethylamine (DETN). The holographic capabilities of
photopolymer performances are determined by the number of functional
groups in the amine molecular structure. There is an optimum
proportion of the photoinitiator, the photosensitizer and the
monomer in the test of holographic parameters with different amine
concentrations. The maximum diffraction efficiency is 59.26\%,
sensitivity is 1.72\times 10^{ - 3}~cm^{2}/mJ, and the maximum
refractive modulation index is 4.64\times 10^{ - 4}. |
