Abstract

La lampe électrique de cette invention possède un récipient de lampe transmettant la lumière (1) dans lequel est logée une source lumineuse (2) possédant un film interférentiel (5) lequel comprend plusieurs couches optiques hautement réfractives et faiblement réfractives. La couche optique hautement réfractive comprend un matériau hautement réfractif avec une structure de rutile et un oxyde mélangé de 96-99 mole % d'oxyde de titane et de 1-4 mole % d'oxyde de niobium. L'oxyde mélangé est de préférence constitué par 97-98 mole % d'oxyde de titane et de 2-3 mole % d'oxyde de niobium. L'invention concerne également un matériau optique hautement réfractif possédant une structure de rutile formée par un oxyde mélangé de 96-99 mole % d'oxyde de titane et 1-4 mole % d'oxyde de niobium. Dans le matériau optiquement réfractif de cette invention, la croissance de la taille de grain est sensiblement retardée durant la durée de vie et la transition de phase d'anatase à rutile est empêchée.
