Interplay of Luminophores and Photoinitiators During Synthesis of Bulk and Patterned Luminescent Photopolymer Blends

Four-dimensional printing with embedded photoluminescence is emerging as an exciting area in additive manufacturing. Micropatterned polymer films containing embedded waveguide channels (or waveguide-encoded lattices, WELs) can be fabricated by localizing incoherent light within a photocurable formulation, with potential applications in solar cell coatings, holographic data storage and optical components. However, as luminophore-photoinitiator …
