Preparation of Polymethyl Methacrylate-NaYF<sub>4</sub>:Yb:Er Composite Material Used for Holographic Display

In this study, we successfully prepared polymethyl methacrylate (PMMA) /NaYF 4 :Yb:Er up-conversion composite luminescence material by solution cast method. PMMA was used for polymer matrix, and NaYF 4 :Yb:Er for rare earth up-conversion luminescence component, and this composite material was prepared for holographic display. Fourier transform infrared spectroscopy (FTIR) and luminescent spectroscopy were measured to analyze structure and luminous performance of the composite material respectively.
