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 .lambda.. The average fiber diameter is comparable in size to the wavelength .lambda. 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.

L'invention concerne un dispositif d'émission de lumière stimulable comprenant un mat de nanofibres présentant un diamètre de fibre moyen compris entre 100 et 2000 nm, ainsi qu'une pluralité de particules stimulables associées aux nanofibres. Les particules stimulables produisent une émission de lumière secondaire lorsqu'elles reçoivent une lumière primaire à une longueur d'onde .lambda.. Le diamètre de fibre moyen est comparable en dimension à la longueur d'onde .lambda., ce qui permet d'obtenir des sites de diffusion à l'intérieur du mat de fibres pour la lumière primaire. L'invention concerne également divers procédés de fabrication de mats de nanofibres luminescents. Ces procédés consistent à effectuer l'électrofilature d'une solution polymère contenant ou non les particules stimulables et à former à partir de la solution électrofilée des nanofibres présentant un diamètre moyen compris entre 100 et 2000 nm. Des procédés, dans lesquels l'électrofilature est effectuée sans les particules stimulables, consistent à introduire pendant ou après l'électrofilature les particules stimulables dans les fibres et donc dans le mat de fibres résultant.
