Patent CA-2758018-A1 (CA)
Inventor: STAATS CORNELIA T
IPC: H01J61/44
Filed: 2010-03-31
Abstract: Cette invention concerne un convertisseur luminescent (10, 12) pour source de lumière enrichie en phosphore (100, 102, 104). Le convertisseur luminescent comprend un premier matériau luminescent (20) conçu pour absorber au moins une partie de la lumière d'excitation (hvO) émise par un émetteur de lumière (40, 42) de la source de lumière enrichie en phosphore, et pour convertir au moins une partie de ladite lumière d'excitation absorbée en une première lumière d'émission (hvl) ayant une longueur d'onde plus longue que celle de la lumière d'excitation. Le convertisseur luminescent comprend, en outre, un second matériau luminescent (30) comprenant un matériau luminescent organique (30) et conçu pour absorber au moins une partie de la première lumière d'émission émise par le premier matériau luminescent, et pour convertir au moins une partie de ladite première lumière d'émission absorbée en une seconde lumière d'émission (hv2) ayant une longueur d'onde plus longue que celle de la première lumière d'émission. Un des effets du convertisseur luminescent selon l'invention est que cette conversion de lumière en deux étapes selon l'invention génère un décalage de Stokes relativement petit de la lumière émise par le matériau luminescent organique. Les inventeurs ont découvert qu'en réduisant le décalage de Stokes du matériau luminescent organique, la largeur du spectre de la seconde lumière d'émission est limitée et réduit une partie infrarouge dans le spectre d'émission. De ce fait, l'efficacité est améliorée.
