Title (EN) WAVELENGTH CONVERTING MATERIAL FOR A LIGHT EMITTING DEVICE
(FR) MATÉRIAU DE CONVERSION DE LONGUEUR D'ONDE POUR DISPOSITIF ÉLECTROLUMINESCENT
Abstract:
(EN) Embodiments of the invention include an infrared-emitting phosphor comprising (La,Gd)3Ga5-x-yAlxSiO14:Cry, where 0 ≤ x ≤ 1 and 0.02 ≤ y ≤ 0.08. In some embodiments, the infrared-emitting phosphor is a calcium gallogermanate material. In some embodiments, the infrared- emitting phosphor is used with a second infrared-emitting phosphor. The second infrared-emitting phosphor is one or more chromium doped garnets of composition Gd3-x1Sc2-x2-yLux1+x2Ga3O12:Cry, where 0.02 ≤ x1 ≤ 0.25, 0.05 ≤ x2 ≤ 0.3 and 0.04 ≤ y ≤ 0.12.
(FR) Selon des modes de réalisation, l'invention concerne un luminophore émettant de l'infrarouge comprenant (La,Gd)3Ga5-x-yAlxSiO14:Cry, où 0 ≤ x ≤ 1 et 0,02 ≤ y ≤ 0,08. Dans certains modes de réalisation, le luminophore émettant de l'infrarouge est un matériau de gallogermanate de calcium. Dans certains modes de réalisation, le luminophore émettant de l'infrarouge est utilisé avec un second luminophore émettant de l'infrarouge. Le second luminophore émettant de l'infrarouge est un ou plusieurs grenats dopés au chrome de la composition Gd3-x1Sc2-x2-yLux1+x2Ga3O12:Cry, où 0,02 ≤ x1 ≤ 0,25, 0,05 ≤ x2 ≤ 0,3 et 0,04 ≤ y ≤ 0,12.
