Their behavior is analyzed in terms of achieved refractive index modulation, dark diffusion mechanism, diffraction efficiency and optical quality; in order to determine their suitability for different holographic applications.engjournal articlehttp://dx.doi.org/10.1063/1.3553840http://scitation.aip.orgopen access535GratingsSolventStorageÓptica (Física)2209.19 Óptica Física
