Abstract

Dispositif pour émettre de la lumière ultraviolette comprenant un barreau (13) muni de nanotubes de carbone, une première couche (11) composée d'un premier matériau cathodoluminescent dans le domaine des radiations lumineuses ultraviolettes UV-C pour une excitation de ce premier matériau cathodoluminescent par des électrons d'énergie comprise entre 1keV et 8keV, une seconde couche (12), composée d'un second matériau métallique, conducteur pour l'électricité, et une chambre (10) composée d'un troisième matériau, transparent pour les radiations lumineuses ultraviolettes UV-C. La première couche (11) est disposée en contact mécanique avec la chambre (10), le long d'une paroi intérieure de la chambre. La seconde couche(12) est disposée en contact mécanique avec la première couche (11). Le barreau(13) est disposé à l'intérieur de la chambre(10), en regard de la seconde couche (12). La seconde couche métallique(12) est d'une épaisseur adaptée à la rendre partiellement transparente pour les électrons d'énergie comprise entre 1keV et 8keV.
