摘要： An article that includes a fluorescent composition having at least one of a fluorescent sensor compound and organic reporter molecules encapsulated in a microsphere structure. When encapsulated, the fluorescent sensor compound and the organic reporter molecules are distributed in a liquid organic matrix. When non-encapsulated, the remaining one of the fluorescent sensor compound and the organic reporter molecules reside in the matrix. In response to a force applied to the composition sufficient to break at least a portion of the microsphere structure, the fluorescent sensor compound and the organic reporter molecules are transformed into a non-reversible fluorescent state exhibiting a quantum yield greater than 0.2. The fluorescent state is objectively visually verifiable without physically contacting the composition.

摘要： A CuInS2@ZnS nanomaterial synthesized with thiosalicylic acid and sodium citrate as dual-stabilizers is taken as a chemiluminescent luminophore, and Tris buffer containing both N2H4.H2O and H2O2 is taken as the triggering solution; introducing the H2O2 into the triggering solution can bring out greatly enhanced CL emission and obviously shortened CL process, enable the CuInS2@ZnS nanomaterial with strong flash-type and near-infrared CL; the luminophore of CuInS2@ZnS nanomaterial is synthesized by a one-pot method; compared with acridinium ester (a classical flash-type chemiluminescent substance), the CuInS2@ZnS nanomaterial is simple in synthesis method, mild in conditions and short in the required time, the synthesized CuInS2@ZnS nanomaterial is not easy to decompose under light, and the CL waveband is in the near-infrared region.

摘要： The present invention provides for a composition comprising a pigment, wherein the composition is suitable for coating a surface that is, or is expected to be, exposed to the sun. The pigment comprises particles that fluoresce in sunlight, thereby remaining cooler in the sun than coatings pigmented with non-fluorescent particles. The particles comprise solids that fluoresce or glow in the visible or near infrared (NIR) spectra, or that fluoresce when doped. Suitable dopants include, but are not limited to, ions of rare earths and transition metals. A coating composition includes: (i) a film-forming resin; (ii) an infrared reflective pigment; and (iii) an infrared fluorescent pigment different from the infrared reflective pigment. When the coating composition is cured to form a coating and exposed to radiation comprising fluorescence-exciting radiation, the coating has a greater effective solar reflectance (ESR) compared to the same coating exposed to the radiation comprising fluorescence-exciting radiation except without the infrared fluorescent pigment. A multi-layer coating including the coating composition, and a substrate at least partially coated with the coating composition is also disclosed. A method of reducing temperature of an article includes applying the coating composition to at least a portion of the article.
