摘要：

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.
