Abstract:
Optically upconverting liquid-filled polymeric materials that are made by curing a curable composition. The materials include a substantially liquid phase that serves to dissolve upconverting chromophores, optionally surfactants and an optionally cross-linked polymer matrix that retains or houses the liquid phase, provides mechanical stability, and offers some protection from oxygen. The optically upconverting liquid-filled polymeric materials have a phase-separated morphology. In preferred embodiments, the domains formed by the two phases are so small that light scattering is largely suppressed, which renders the upconverting liquid-filled polymeric materials largely transparent. The liquid phase provides a high mobility of the dissolved chromophores and the photophysical properties, such as the high upconversion quantum efficiency and the low excitation intensity threshold required to achieve upconversion, are thus more reminiscent of conventional or oxygen-free solutions than polymeric solids. These photophysical properties can be achieved by preparing the polymers under oxygen-free or, in preferred embodiments, under ambient conditions. The design principle introduced here to create upconverting liquid-filled polymeric materials is versatile and general; the liquid phase, the surfactants, the polymer matrix, and the upconverting chromophores can all readily be varied. Importantly, the optically upconverting liquid-filled polymeric materials can be prepared in a one-step process, which makes them preferable over other liquid-containing polymers that enable upconversion.

Claim (Index 22):
The light upconverting phase-separated material according to  claim 1 , wherein said light-upconverting phase-separated material is substantially transparent, wherein preferably the phase-separated material displays a transmission of at least 85% measured over a path length of 1 cm at any wavelength between 415 and 670 nm; in which the liquid phase or phases forms or form domains with dimensions of maximally 30 nm; wherein said solid phase contains at least one polymer in an amount of at least about 80 wt % based on the total weight of the solid phase; wherein said at least one liquid phase is present in an amount of up to 30 wt % based on the combined total weight of the material; wherein said at least one liquid phase includes at least one hydrophobic liquid in an amount of at least about 10 wt %, based on the combined total weight of the material; wherein said at least one hydrophobic liquid has a boiling temperature of more than 250\u00b0 C.; wherein said at least one hydrophobic liquid has a solidification temperature of less than 0\u00b0 C.; wherein said light-upconverting phase-separated material contains at least one cationic, nonionic or anionic surfactant preferably in an amount of from about 2 wt. % to about 15 wt. % based on the total weight of the material and which is characterized by an upconversion quantum efficiency of at least 0.05.
