In this study we developed an approach to improve the characteristics of photopolymers for holographic data storage. Through codoping different compounds, N , N ‐dimethyl‐4‐nitroaniline (DMNA) and zinc methylacrylate (Zn(MA) 2 ), into 9,10‐phenanthrenequinone (PQ) doped poly(methyl methacrylate) (PMMA), the diffraction efficiency and the value of dynamic range (M#) have been progressed. We enhanced the diffraction efficiency (from 36.1 to 86.2%) and the dynamic range (M#, from 2.9 to 10.7) of PQ‐doped PMMA through codoping with DMNA and Zn(MA) 2 . Using mass spectrometry and X‐ray photoelectron spectroscopy, we investigated the mechanism behind the improvements in optical storage induced by the presence of Zn(MA) 2 and DMNA in PMMA/PQ. POLYM.
