| Abstract: | Transparent light‐emitting hybrid materials are produced by UV curing of acrylic resins containing silica precursors and photoluminescent Cu4I4L4] clusters. Acrylic double‐bond conversion is followed by means of FT‐IR spectroscopy, and optical measurements are performed on cured films showing a high transparency of the films up to a content of 30 wt% TEOS and a bright luminescence with a maximum of emission centered at 565 nm (yellow‐orange). This study shows the possibility to obtain new advanced materials in which functional properties such as photoluminescence and scratch resistance are successfully conjugated in a hybrid film that maintains high transparency.  |
