Nonlinear optics: Photoinduced interfacial polymerization within a microfluidic channel is shown to be an effective method to prepare microcapsules that provide for photon upconversion by triplet–triplet annihilation (see picture). In this approach, an elastomeric shell formed on the inner surface of the microcapsules served as an efficient protective shield, whereas a liquid core promoted the required energy transfer for the upconverted luminescence.
