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 30wt% TEOS and a bright luminescence with a maximum of emission centered at 565nm (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.

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 30wt% TEOS and a bright luminescence with a maximum of emission centered at 565nm (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.
