    Abstract: A fiber-based reflective lighting device. The lighting device includes a source configured to generate a primary light, a substrate including a mat of reflective nanofibers, and a light exit configured to emanate the reflected light. The fibers have an average fiber diameter AFD less than 500 nm which diffusively reflects visible light upon illumination with at least the primary light. The mat has a basis weight less than 40 gram per square meter (gsm) and a reflectance greater than 80%.

    Abstract: A device for stimulable light emission that includes a fiber mat of nanofibers having an average fiber diameter in a range between 100 and 2000 nm, and includes plural stimulable particles disposed in association with the nanofibers. The stimulable particles produce secondary light emission upon receiving primary light at a wavelength λ. The average fiber diameter is comparable in size to the wavelength λ in order to provide scattering sites within the fiber mat for the primary light. Various methods for making suitable luminescent nanofiber mats include: electrospinning a polymer solution including or not including the stimulable particles and forming from the electrospun solution nanofibers having an average fiber diameter between 100 and 2000 nm. Methods, which electrospin without the stimulable particles, introduce the stimulable particles during electrospinning or after electrospinning to the fibers and therefore to the resultant fiber mat.
