Abstract
The development of new holographic materials represents a field of research in continuous evolution. The design and synthesis strategy of these materials must respond to the desirable characteristics of the photonic devices that need to be manufactured. Hydrogels are used as binders in applications in which the material must retain its structural integrity in liquid media. In applications where it is required to store volume holograms in hydrogels, it is necessary to carry out a first incubation process in solutions containing the necessary components. The general aim of this work has been to optimize the composition of incubator solutions composed of acrylamide as monomer, N,N′-methylenebis(acrylamide) as crosslinker, triethanolamine and yellow eosin as photoinitiator system and DMSO/water as solvent. The effect of varying the monomer and crosslinker on the diffraction efficiency of stored holograms has been investigated.

Belén Nieto Rodríguez graduated in Physics at the University of Alicante (2022). During the degree she acquired learning skills in programming languages such as Python, Matlab and Fortran, in addition to a large load of mathematical subjects. During the 2021-2022 course of the Degree in Physics at the Complutense University of Madrid, where he took the subjects of Photonics and Energy and Environment. He attended congresses, seminars and courses oriented to Photonics and Education. She is currently working as a Laboratory Technician in the Department of Optics, Pharmacology and Anatomy (University of Alicante) in a project focused on the study, design and characterization of holographic optical elements for different applications (photovoltaic energy, sensors, and image-forming optical systems). She is also an associate professor in the Department of Physics, Systems Engineering and Signal Theory at University of Alicante.
