The PET may further include electrospun polypropylene nanofibers (PPNF) incorporated therein. In some embodiments, the photochromic material may be transparent. In other embodiments, the photochromic material may be scratch resistant. In some embodiments, the photochromic material may be configured to form concrete. In still other embodiments, the photochromic material may be configured to form windows. The electrospun polypropylene nanofibers may be a roughening agent in the PET. The photochromic material may exhibit a green coloration after exposure to ultraviolet (UV) light. The NLSA may have a diameter of about 80 nm to about 120 nm.

摘要： Disclosed is a light-emitting device provided with a solid-state light-emitting element and a phosphor and emits output light. The spectral distribution of the output light has a first light component and a second light component derived from fluorescence emitted by the phosphor, and has a first minimum value between the first light component and the second light component. The first light component is a fluorescent component having a maximum intensity value within a wavelength range of 560 nm or more and less than 700 nm. The second light component is a fluorescent component having a maximum intensity value within a wavelength range of 700 nm or more and less than 2500 nm. The maximum intensity value of the second light component is greater than that of the first light component. The first minimum value is less than 50% of the maximum intensity value of the second light component.

摘要： Ruggedized luminescent nanoparticle tracers have luminescent nanoparticle cores coupled to a luminescent substrate. The substrate is a large-particle size phosphor, while the nanoparticles are photoluminescent quantum dots (QDs) whose emission spectra can be tuned based on their chemical composition, size, and fabrication (e.g., dopants). The QDs are encapsulated by a protective layer to form a nanoparticle core. The protective layer can shield the QDs from external environments that would otherwise damage the delicate QDs. The substrate is also encapsulated by a protective layer, and the protective layer of the nanoparticle core is coupled to the protective layer of the substrate via a molecular linker to form a tracer particle complex. The tracer particle complexes can be disposed in a silicate suspension for subsequent use.

摘要： An emission enhancement structure having at least one energy augmentation structure; and an energy converter capable of receiving energy from an energy source, converting the energy and emitting therefrom a light of a different energy than the received energy. The energy converter is disposed in a vicinity of the at least one energy augmentation structure such that the emitted light is emitted with an intensity larger than if the converter were remote from the at least one energy augmentation structure. Also described are various uses for the energy emitters, energy augmentation structures and energy collectors in a wide array of fields, including various adhesives applications.
