A chromic luminescent composition and method for fabricating the composition are disclosed. The chromic luminescent composition comprises at least one or more non-luminescent materials and one or more luminescent materials. The one or more non-luminescent materials having absorption spectra that at least partially overlap with the spectrum of incident electromagnetic radiation. The one or more luminescent materials convert at least a portion of energy of incident electromagnetic radiation to a lower energy wavelength. The one or more non-luminescent materials and the one or more luminescent materials are selected such that, when subsequently exposed to incident electromagnetic radiation, color and brightness are substantially modulated through absorption and emission as a function of incident electromagnetic radiation. Also disclosed are a chromic luminescent textile and a method for fabricating the textile.
摘要:
An illuminator and a method for fabricating the illuminator are disclosed. The illuminator comprises at least a light source and a discriminator. The light source comprises one or more luminescent layers that substantially convert the energy of a primary electromagnetic radiation to an output radiation. The discriminator comprises one or more layers that substantially transmit the primary electromagnetic radiation to the one or more luminescent layers and reflect at least a portion of the output radiation from the one or more luminescent layers to the viewing hemisphere. A method for applying the illuminator to an object is also disclosed.
摘要:
A photoluminescent marking that includes a photoluminescent layer and at least one functional overlayer is disclosed. The photoluminescent layer comprises at least one type of photoluminescent material. The at least one functional overlayer is adapted to selectively filter wavelengths of radiation to enhance the daylight observability of a final emission signature of the marking or to prevent the observability with the naked eye of a printed message on the marking. Also methods of making and using the inventive photoluminescent marking are disclosed.
