| Abstract | Light emitting diode (LED) structures with an overstructure material having a refractive-index matched to the active layer and ways to produce such materials are disclosed. Various implementations of such structures to provide very high extraction efficiency and color control such as white light emission are also disclosed.
L'invention présente des structures de diode électroluminescente (DEL) dotées d'un matériau disposé sur la structure ayant un indice de réfraction correspondant à la couche active et des procédés de production de tels matériaux. L'invention présente également diverses implémentations de telles structures permettant d'obtenir un rendement d'extraction très élevé et un contrôle de la couleur tel qu'une émission de lumière blanche. |
